Improved Reproducibility and Reduced Sample Preparation Time for the HPLC Analysis of Aflatoxins in Raw Peanut Paste

The US FDA and international regulatory agencies have set contamination levels for aflatoxins in animal feedstuffs. Since Aspergillus may infect commodities pre-harvest, during storage or during processing, monitoring for aflatoxins in associated agricultural commodities at all stages of production is requisite. Field screening methods exist that are adequate to estimate contamination levels for aflatoxins. When additional confirmation or quantification is desired, chromatographic laboratory analysis is often...

Sample preparation and pumping systems for wastewater treatment industry

A wide range of sample acquisition and filtration systems are available to prepare even the most difficult of samples for reliable on-line analyser measurement. The correct choice is often critical to prevent analyser blockage and optimise performance. Cross Flow Filtration The PPM cross flow filter, is a simple in-line device used to protect an analyser from ingress of solids, for applications where sample quality is generally good but occasionally suspended solids may be present. The stainless steel filter...

Analysis of Herbicides in Drinking Water

Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources. While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple analytes, but also in part due to the variety of HPLC stationary phases...

Determination of Additives in Beverages using Ascentis Express Columns

Beverages, such as sodas and energy drinks, can include a number of polar ingredients, which are easily soluble in the water matrix of the drinks. These ingredients include sweeteners (sugars and sugar substitutes), caffeine, vitamin supplements, amino acids, organic acids, and plant extracts. Because the analytes are already in solution, there is no need for extensive sample preparation. Dilution followed by direct injection into an HPLC is typically suitable. In this article we present two beverage applications...

RAPID ANALYSIS OF TOTAL MERCURY IN WASTE WATERS AND PROCESS WATERS WITH ELEVATED MERCURY CONTENT USING DIRECT PYROLYSIS TECHNIQUE

A conventional standard method of total mercury determination in water using atomic absorption spectrometry (AAS) involves preliminary sample digestion that takes from 30 minutes to 8 hours depending on the digestion conditions. The use of a mercury analyzer RA-915M/RA-915+ with Zeeman background correction in combination with PYRO-915+ pyrolysis attachment provides direct determination of mercury in process and waste waters contaminated with mercury without digestion or any other sample preparation stages. The...
