As global supply chains grow more complex, protecting food quality and reducing risk depends on reliable analytical methods and automated sample preparation solutions for a safe, sustainable food system. This article shows how techniques like SPE and IAC—especially when automated with ASPEC® systems—boost throughput, reduce variability, and deliver accurate, reproducible results across even the most challenging food matrices.
What if automating food safety testing didn’t mean sacrificing accuracy? See how Gilson’s ASPEC® 271 and R-Biopharm Rhône’s OCHRARHONE® WIDE AUTO columns simplify ochratoxin A testing in cereals and spices. This validated, fully automated workflow delivers precise, reproducible results while freeing your team from tedious manual cleanup.
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic compounds that have been widely used since the 1950s and are found in the environment and in the food supply. Because of the longevity of these chemicals, they pose a risk to human health through food and tap water consumption and other exposures. In order to understand the magnitude of the problem and to ultimately protect public health, regulatory agencies in various countries regularly detect and analyze PFAS in the food supply.
In this article, we provide an overview of GPC and how it’s used for post-extraction cleanup including: how GPC works, the components of a GPC system, and a step-by-step look into the GPC process
Per- and polyfluoroalkyl substances (PFAS), or “forever chemicals”, are highly stable materials used in a variety of household products, industries, and processes. These chemicals can pose several health risks to living organisms and contaminate the environment. In this article, we elaborate on the above along with how automated solid phase extraction can be used to isolate PFAS from numerous matrices including water, soil, air (dust), and food such as seafood and eggs.
Central Nervous System (CNS) depressants can introduce calm and induce sleep. Benzodiazepines are CNS depressants used to relieve anxiety, insomnia, and panic attacks. This application note discusses a simple SPE urine extraction before LC/MS-MS to confirm the presence of 15 spiked benzodiazepine analytes.
As you go through the steps of SPE method development or transferring a manual method to your automated system, reference this guide as both a resource and step-by-step troubleshooting handbook. This guide provides a background for the technique and explains the science of solid phase extraction (SPE). It also offers practical advice for automating workflows via Gilson SPE systems and software.
Automating protocols with liquid handlers provides repeatability and gives you greater confidence in your results. Here's a quick overview of automated SPE.
Analyzing the use of AttractSPE WAX-PFA cartridges with the Gilson 274 ASPEC Large Volume System to automate the SPE of PFAs from tap water samples.
Manual sample preparation and treatment is a laborious process requiring constant attention in the lab. Here’s how to optimize and automate your SPE workflows.
