Raptor™ ARC-18 LC Columns

Great column for my application, good separation, non-bleed.

The Raptor ARC-18 column is one of the best columns for cannabinoid analysis. The separation for multiple cannabinoids is so great even by using the isocratic condition. Strongly recommended.

The column came in very fast. It has easy to understand instructions. It is nice to see that CofAs are available online, less paper. The separation was top notch. As per the paper Restek published earlier, the chromatogram did not disappoint. All peaks were sharp, nicely separated and a very fast run. Extremely satisfied so far. Unfortunately, we are in the process of renovations, so we can not perform many runs right now. Due to that fact I can not comment of how durable the column is. When I had questions about storage of the column, the customer service representative was very quick to respond with very informative explanations. Overall, pleased with the purchase.

Achieved good separation of many different CBD compounds.

I have had a look at a number of columns that could be used in cannabinoid analysis, the Raptor ARC-18 was the first and only column that reproduced the described manufacturers method. Following the manufacturers method this column was able to reproduce the method in our laboratory and has continued to do so.

I've found the ARC-18 LC columns are the best column for potency analysis in cannabis products. Similar columns from other manufacturers did not get the same resolution as this column. It is robust and lasts for many injections.

This column was not the easiest to get set up. I cannot get my peaks to look anywhere as clean as the website shows. I have asked for advice a few times and nothing has really helped. I will keep doing my own R&D to figure out how to improve my peaks. I also would have figured that I would have gotten a notification when the standard procedure changed and the cannabinoid profile expanded. This is a missed opportunity because there could have easily been an up sale. Additionally, I am a customer that will go out of my way to stay with a company and promote them to other people in my industry if I feel that they go above and beyond to ensure that all my needs are met. For instance, I have definitely pushed several of my colleagues to start going through GenTech because of their superb customer care.

This product is very effective for our use in separating, identifying and quantifying 9 cannabinoid compounds in a large array of products. We have developed a series of methods using the Restek Raptor ARC-18 columns, starting with the 5um particle size then moving down to the 2.7um particle size. We were even given the 1.8um to demo but did not have enough time for method development so would need to revisit the application. Regardless, it is a great product that is commonly used across the industry with a great reputation for THE column to use for cannabinoid analysis.

The Arc-18 column has acceptable separations but the robustness of the column and the resistance to clogging is outstanding.

I cannot work without the Restek Raptor ARC18 column that I use daily for my testing needs. Lifespan is great especially with adding on the guard as an option. It is perfect for what I am testing and I would never go back.
