Reversed-phase HPLC columns have been widely used due to their superior resolution, high theoretical plate number, ease of use and good cost performance.
Octadecyl silica gel (C₁₈, ODS) is the most commonly used by chromatographers. In reversed phase HPLC columns, hydrophobic interaction is the dominant separation mode. For some substances similar in hydrophobicity, recognition capability may be poor, resulting in insufficient separation.
The COSMOSIL PYE and NPE columns utilize various interactions based on electrons of the stationary phase. The PYE and NPE columns can be widely used for the separation of substances similar in structure.

CHARACTERISTICS

The COSMOSIL PYE column is a reversed phase column. Its stationary phase is planar pyrene or 2-(1-pyrenyl)ethyl groups bonded chemically to the silica gel. Utilizing –interactions originating from the pyrene ring, the PYE column separates substances similar in structure.
The COSMOSIL NPE column is also a reversed phase column, which contains nitrophenylethyl groups chemically bonded to the silica gel. The NPE column provides unique retention characteristics somewhat different from the PYE column, utilizing both dipole-dipole and –interactions.

SEPARATION OF PAHS

C₁₈ columns have been commonly used for the separation of polycyclic aromatic hydrocarbons. However, their resolution for the separation of isomers is limited. Due to the electrostatic interaction between the sample (eg. benz[α]anthracene and chrysene) and the pyrene ring in the stationary phase, the COSMOSIL PYE packed column can achieve the separation of aromatic isomers.

SES Research Inc has created some amazing products that I have absolutely loved trying and using! My vital c focus & energy has helped me to fall asleep faster and stay asleep longer, and my concentration has improved. ESS60 has such awesome studies and results I'm so glad I found this company. Their face serum is also doing wonders for my facial skin, it's moisturizing and I haven't had any pimples since I started using it! I definitely recommend this company and their products!

Breanna is amazing, knowledgeable and provides thoughtful customer service. She is truly committed to providing a great outcome of a bad situation. I have interacted with her to reorder and to help resolve missing orders. If I were her boss, she is the perfect example of the employee I would be looking to hire. Thank You Breanna for you excellent service and always having the customers back. SES is a great product and you have a great employee in Breanna.

I am 83 years old and have been taking C 60 for about 2 1/2 years. The doctor I see once a year for yearly Medicare checkup says “I am one in a hundred”. I have no physical ailments and take no medication. (Of course, he does not know about my taking C 60.) my eyesight has actually been improving rather than getting worse with age and I can do many physical activities that my friends who are many years younger cannot.(I also recommended your C 60 product to three of my friends, who are now your customers.)

Wonderful product and super customer service. Joanna in CS was a great help, first in answering my email, and then in answering my phone call. There are generous and flexible product buying options not always mentioned in SES advertising emails that really show what a quality company SES works hard to be.

I have just recieved the product. I'm a cancer patient so I went with the higher quality olive oil. It does seem to have a decent amount of oleocanthal because it does have a peppery taste in the back of your throat. The taste is pleasant to me. For those who don't know, you only taste this upon swallowing.

I had a customer service question. Joanna explained what the solution was, and that I was not entitled to what I thought that I was. She did an excellent job.ThanksP.S. I do not expect to always be right. I only expect professionalism, and politeness in any explanation. That is what I got. Excellent customer service.

Outstanding customer service!Jessy is knowledgeable and finds the most cost effective solution to any queries I have.Apart from being the best product on the market it is matched by the best customer service.This is feedback for Breanna,I am astonished how the great customer service I received got even betterBreanna dealt brilliantly with a quite complex order. Hugely accomodating to my request.I'm not easily pleased but Breanna provided the best customer service I've ever received.Can't praise her enough. I know I'll receive exactly the same service again.

First of all, SES is the top manufacturer of c60 products. They have been researching and producing fullerenes for 30 years, which is longer than any company currently in business. Their products were used in the original study that demonstrated the longevity benefits of c60, and their products continue to be used as reference samples and controls in ongoing research about c60 and c60 oil products. I am healing from a poorly understood chronic illness for which the best treatment option is lifestyle changes and antioxidant therapy. C60 is now my antioxidant of choice because I can feel monumental system-wide changes after only a week of daily c60 use, and I often notice the benefits of this compound within seconds of ingesting it. C60 is a true wonder drug as far as I’m concerned, and SES Research is the best source. Do your own research and you will find that Chris and his team are doing it better than anyone else. Big thanks to Joanna for great customer service, and thanks SES RES for the medicine that is helping to turn my life around.

I've been taking it for almost two months. I feel less tired and my sleep has improved.I had a big stock and wanted to put on hold my account. Joanna from customer service was very helpful and courteous helping me with this issue.

Bernard Chan

The C60 quality has been great and very well packaged. What was even more impressive and unexpected was the level of customer service (especially Breanna) - really prompt, patient and felt unscripted. Other companies take note, this is how you win long-term customers. One request, consider offering more no duty rate options (150ml and cases) up in Canada.

Joanna at SES customer service was awesome! I had purchased and tried C60 fine-grade olive oil with good results. My deep sleep score doubled when I began taking it (I measure sleep with an Oura ring). Sleep is so important to me, I was thrilled. A friend and Ph.D. researcher forwarded a published study that was done using the C60 molecule and olive oil resulting in unfavorable outcomes. I was concerned and sent a note to SES Research asking if they were aware of this study. Joanna responded within an hour pointing out in detail the discrepancies in protocols between the studies. Honestly, I didn't expect that I would hear back from SES Research. Her quick detailed response really up'd the score on my trust meter.

Customer service is the best! I've had two problems with shipping and Joanna took care of them immediately no questions asked. I'd hope other companies would be to lucky to have her on their team, the best!Now I have tried SES before and their wonderful product DOES hold up to their advertisement on what it does, each time I take a dose it's like having comfort food, that warm fuzzy feeling you get, just love the feeling gained by using the product. My recommendation, You deserve the best in life especially for your body, SES will give you that. You'll have many health benefits, not only the highest grade product and totally bar none, Joanna will handle any problems that could arise, the best!My thanks to SES and Joanna at customer service, you're the greatest,Dale Reynolds

I love the Carbon 60 that we purchase from SES Research. The flavor is great and while we don’t notice a big difference on a day-to-day basis, but we do realize a difference on the days where we don’t take it. We just don’t feel as limber and energetic. When we are sick, and it makes a HUGE difference.I also have received excellent customer service from Jesse. One of our bottles on auto ship came with a broken seal, and they are sending a replacement bottle. This company is also really good at delaying your auto ship for months out if you feel like you have too much product on hand. We’ve been ordering from SES Research for over a year now, and before that we were taking C60 that our natural health practitioner was making for over a year. We definitely feel like C60 from SES Research is better with the consistency and quality.

SES products are the best I have had nothing but positive responses from their products and the last product I ordered I received it in just two days. I really don't know how they do that, but it is fantastic, I would recommend their products to everyone...I had planned on living to the age of 100y/o but now with taking the SES-c60 they say it can possibly double your age so I'm shooting for 200y/o. You never know...Thank you SES Research Dan

SES Research is the original source of c60 in the US and they continue to offer a solid, quality product that it easy to dose correctly and use daily. Their customer support is very responsive and professional and will go the extra mile to ensure you have a positive experience. I recently had multiple issues with FedEx delivering my last order. Luckily, the SES representative stepped in on my behalf and coordinated things so that I was able to get my order delivered. It made all the difference. Hopefully they'll use UPS in the future rather than FedEx. Highly recommend their c60 in fine grade olive oil!

Jerry Escalante very readily and courteously helped me resolve a delivery product with my order, resulting in delivery that same afternoon after FedEx had said it was already delivered. Thanks, Jerry! I took my first dose last night and slept very well. Looking forward to tracking my progress! Thanks to the whole SES Research team for a great product, and great service. As I live in San Antonio, I'm happy to support a Houston, Texas-based business, too!

From the first phone call I made to inquire about this product to now - over a year later - they have been great! Someone picks up the phone, (no robots or "press this #) : ) They always get my order or requests correct the first time!! I wish more companies were like them. Thank you !

Jessy was very kind and helpful. I love the product. It gives me energy, calmness, improves my sleep, and overall well-being. I even love to put it on my skin. I give it to my dog as well, and he is energetic, his fur is velvet soft, and I have even noticed a small growth completely reverse. Thank you for being so transparent and honest. Best C60 around. Thank you again for the amazing customer support, and top notch quality.
