Gilson Connect
In this application note we examine the limits of quantification and detection, repeatability, reproducibility, and recovery in food safety analytical testing. Automation with the GX-271 ASPEC® system provides a reproducible and
reliable method for the isolation.
In this application note, three glucocorticoids and three nonsteroidal anti-inflammatory drugs were detected simultaneously from horse urine using the Gilson GX-274 ASPEC® system with two step extractions and LC/MS/MS selected reaction monitoring (SRM).
Deoxynivalenol (DON) is a mycotoxin that occurs predominantly in grains such as wheat, barley, oats, rye, and maize and consumption is associated with outbreaks of gastroenteritis in humans. Automated methods are well-suited for quantification of toxins because they are accurate, reduce the time required for laboratory analysis, and reduce human errors - learn more in this application note.
Nitrosamines are a class of semi-volatile organic chemical compounds characterized by a nitroso group attached to an amine group. In this tech note we describe a method for automating US EPA Method 521 using the Gilson ASPEC® 274 Large Volume System
Δ9-tetrahydrocannabinol and its metabolites are essential for drug testing. GC/MS is often used for quantification of Δ9-tetrahydrocannabinol, however, it is time consuming. Rapid methods that maintain the sensitivity and selectivity of GC/MS are desirable - learn more in this application note.
Per- and poly-fluoroalkyl substances (PFAs), sometimes referred to as perfluorinated compounds, are a family of molecules consisting of varying lengths of fluorocarbon chains with a functional group such as carboxylic or sulfonic acid attached. This application note describes the automation of the isolation of 10 PFAs from tap water prior to their analysis by LC/MS.
Since 1970, glyphosate has been used as a systemic, non-selective herbicide and crop desiccant on farms, in fields, and in public and residential areas. This application note describes the rapid purification of glyphosate, aminomethylphosphonic acid (AMPA), and glufosinate from red wine using AFFINIMIP® SPE Glyphosate.
This application note describes a high throughput sample preparation procedure for global glycan mass profiling.
As globalized food trade has become more common in recent years, improved screening methods combined with food inspection investigations have put a large amount of pressure on the food and beverage industry to improve quality assurance and control. This pressure led to the FDA Food Safety Modernization Act (FSMA), which aims to ensure the U.S. food supply is safe by shifting the focus of federal regulators from responding to contamination to preventing contamination.
Mycotoxins are toxic compounds produced by fungi that are harmful to humans and animals. Patulin, found in rotting apples, is a compound that is regulated in many countries. Food safety testing for patulin is crucial to limit exposure; however, many sample cleanup methods do not remove closely related compounds, which can lead to false positive results.
