The nutrition profile of food is critical for assessing its quality. In this poster the amino acids in soy flour were hydrolyzed using a Discover Prep microwave system.

Plant-based proteins are becoming a mainstay to grocery stores, restaurants, and retailers. Amino acids in vegan cream cheese are herein hydrolyzed and analyzed.

In this app note, we perform amino acid hydrolysis of proteins to identify and quantify each amino acid utilizing a safe and rapid amino acid hydrolysis protocol.

Protein analysis plays a large role in the production of foods, pet foods, and even pharmaceutical medicines. But first, the amino acids in the protein must be broken down.

Peptide therapeutics are held to high regulatory standards. Discover Prep was used to hydrolyze the amino acids of a peptide in only 15 minutes, instead of 24 hours.

Classical protocol of amino acid hydrolysis needs up to 24 h of reaction time. Using the Discover Prep, the same level of acid and base hydrolysis was achieved in minutes.

Wed, Oct 26, 2022 11:00 AM EDT Plastics are an integral part of everyday life but analyzing their composition can be a challenge. Tune in to learn about a variety of extraction techniques that will increase sample throughput while yielding superior sample prep.

This application note demonstrates the performance of the miniLC LC–UV analyzer for the analysis of catechins and epicatechins in teas.

Pesticide testing is crucial to assessing the safety of fruits and vegetables for consumption. The traditional extraction method for pesticides from produce is the QuEChERS method. This method is tedious, manual, time consuming, and wasteful. Thus, there is a need for improved methods of extraction. In this application note, the EDGE®, in combination with Q-Matrix™ Hydra, a water-removing sorbent, was used to extract a panel of pesticides from 10 g of homogenized cucumber, tomato, and green pepper in less than 9 min. The recoveries of the pesticide panel were greater than 70% for each matrix tested, and these results were highly reproducible. The EDGE provides a fully automated extraction that combines both the sample and sorbent into one sample vessel, alleviating the human burden of extraction and the need for multiple sample transfers.

In order to evaluate and test the robustness of cannabinoid analysis using the miniLC, a method was chosen from the literature and compared to data from the miniLC system. Comparison of retention time of standards to published values indicates the miniLC provides an excellent alternative with comparable results to a more expensive, complicated liquid chromatography system

A few hours of your time will deliver enormous benefits for your work.

Automated liquid extraction of pesticides from tea that eliminates the use of salts and sorbents. In less than 15 min, get filtered sample that is ready for analysis.

Extract pesticides from cannabis flower and edibles with one simple automated method. In less than 15 minutes you will be ready for analysis and on to the next sample.

***Thursday and Friday May 13-14 | May 20-21, 2021*** In the relaxed and unconventional talks in this symposium, highly experienced speakers from industry and academia will impart key learnings from their long experience with chromatography—from heroic failures that have taught them valuable lessons, to moments of inspirational serendipity, and everything in between. CHROMTalks will deliver lifetimes of learning in condensed form, covering topics across implementation, troubleshooting, and method development of analytical techniques. Time spent at CHROMTalks will pay back as soon as you enter your laboratory! ***Available On Demand Until May 21, 2022***
