What if automating ochratoxin A testing in wine could improve both efficiency and confidence? Learn how a validated, fully automated workflow using ASPEC® 271 and OCHRARHONE® WIDE AUTO columns ensures precise, reproducible results while minimizing operator variability.

This application note demonstrates how automated immunoaffinity cleanup enables reliable, reproducible quantification of ochratoxin A in cocoa by standardizing sample preparation and reducing variability. The validated workflow delivers high accuracy (80–110% recovery, ≤5% RSD) while improving efficiency and minimizing human error in food safety testing.

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.

Expand your system’s capabilities with precision temperature control and flexible labware support—all fully automated for increased efficiency and reliability.

Many sample types, such as those from the environment or food, undergo testing to detect contaminating residues such as pesticides, antibiotics, chlorinated hydrocarbons, and compounds of health concern. While the exact governmental regulations surrounding testing methods differ by country, gel permeation chromatography (GPC) is one of the routine methods used to clean up samples before analysis. As a routine step in residue testing, is often a part of the workflow to prepare samples before analysis by a variety of chromatography methods such as GC, HPLC, or LC/MS. GPC removes unwanted substances such as lipids, proteins, cell debris, pigments, humic acid, and sulfur, that can interfere with downstream chromatography steps used to detect the residues. Including GPC cleanup in residue testing can help make chromatography columns last longer, protect instrumentation, and improve residue detection accuracy.

Plastics are ubiquitous in our society and are extensively used in a large variety of packaged foods. There is currently a great deal of interest in measuring the migration of these compounds into food products, as considerable uncertainty exists regarding the human health risks associated with exposure to such compounds. This application note describes the use of gel permeation chromatography (GPC) cleanup to separate a variety of plastic additives from a representative edible oil sample prior to analysis.

ICP-MS analysis is a technique of choice in many laboratories to quantify trace elements in many matrices. Automating this process reduces manual handling errors and provides traceability where manual preparation has none. This technical note shows how the use of a Gilson liquid handler and TRILUTION® LH Software makes it possible to automate those acidic dilutions prior to analysis by ICP-MS.

Post-extraction cleanup methods are commonly used in residue analysis workflows. The methods vary and the choice of method can depend on many circumstances: the type of sample, type of analyte, and regulatory requirements. This article focuses on two chromatography-based methods for post-extraction cleanup: gel permeation chromatography (GPC) and solid phase extraction (SPE).

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
