This document introduces the method for detecting fumonisins using Agilent 1100 Series LC/MSD without derivatization.

The X9409 is a low noise, low power, 2-wire bus quad digitally controlled potentiometer (XDCP). It features four potentiometers per package with 64 resistor taps. It supports a 2-wire serial interface for write, read, and transfer operations of the potentiometer. The operating voltage range is from 2.7V to 5.5V. It has non-volatile data registers and non-volatile storage of multiple wiper positions. The saved wiper position is loaded on power-up.

Triglycerides are the major components in edible oils. This note describes a method for analyzing intact triglycerides by LC/MS and the type of information available.

A Method Used to Screen for 567 Pesticides and Suspected Endocrine Disrupters

This paper introduces a HPLC method based on reversed-phase chromatography and UV-visible diode-array detection for the determination of tetracyclines in meat. The method is simple, sensitive, and suitable for the large-scale determination of samples.

This application note describes a method for analyzing pesticides at the trace level using large-volume injection (LVI) with the Agilent programmable temperature vaporizing (PTV) inlet. With LVI, the detection limit of gas chromatography systems can be improved by one to two orders of magnitude over standard methods that require 1- or 2-microliter injections. An Agilent 6890 Series gas chromatograph (GC), configured with a PTV inlet, an Agilent 6890 Series automatic liquid sampler (ALS), and an Agilent 5973 mass selective detector (MSD), was used for the analysis of pesticides in standards and several food extracts. By making 100-microliter injections, several pesticides could be identified by scanning gas chromatography/mass spectrometry (GC/MS) at the 100 ppt (100 ng/L) level. The PTV inlet tolerated dirty food extracts very well; more than 1,500 microliters of such samples were injected into a single PTV liner. This application note includes recommendations for performing LVI using the PTV/6890/5973 GC/MSD system.
