The document introduces an automated sample preparation method for LC/MS/MS analysis of compounds in biological matrices using protein precipitation. The author presents a new protein precipitation filtration plate, Captiva ND, introduced by Agilent, which utilizes non-drip technology for simple operation and improved sample preparation efficiency.

This application note describes a method for the determination of calcium and magnesium in blood serum and urine using atomic absorption spectrophotometry.

This application note introduces the use of the Agilent Select Biodiesel for Methanol column for the quantitative analysis of methanol in biodiesel. Using the Select Biodiesel for Methanol column, mixtures of biodiesel that contain other low boiling components can be analyzed with good reliability.

This application note describes the EN-14103 method for determining the total fatty acid methyl esters (FAME) and linolenic acid methyl ester content in biodiesel.

Agilent's new DialPath technology is the first major breakthrough in FTIR transmission measurements of liquids in decades. The DialPath technology makes longer pathlength transmission measurements as easy and quick as ATR makes short pathlength liquid analysis. This sampling accessory has three individual pathlengths that can be accessed in seconds, and is a significant new sampling methodology that simplifies both quantitative and qualitative analysis.

This document discusses the importance of accurate and precise determination of gold and other precious metals, and introduces the new method using Agilent 4100 MP-AES to meet this need.

This document describes the analysis of trace elements in petro-diesel and biodiesel fuels using the Agilent 4100 MP-AES. The instrument is capable of stable analysis of organic matrices and eliminates the need for expensive and dangerous gases, resulting in lower running costs and improved productivity.

This application note describes a method for measuring additives in lubricating oils using the Agilent 4100 Microwave Plasma Atomic Emission Spectrometer (MP-AES). The MP-AES is a fast, multi-element technique that is capable of high sample throughput, making it an ideal method for measuring additives in lubricating oils.

This document introduces the Triggered MRM Acquisition method, which can simultaneously quantify and confirm target proteins.

This document describes the application of the Agilent 6550 Quadrupole Time-of-Flight (Q-TOF) Mass Spectrometer for high sensitivity peptide analysis. The Agilent iFunnel technology combines highly efficient electrospray ion generation and focusing with a hexabore capillary sampling array and dual-stage ion funnel to increase ion sampling and transmission. This innovative design allows for a 10-fold increase in sensitivity for selected molecules compared to an earlier generation Q-TOF instrument without iFunnel technology.

This document describes how to use the Agilent 1260 Infinity LC system to detect four pesticides in honey

FTIR spectrometers employing attenuated total reflection (ATR) sampling interfaces are proven and powerful tools for the analysis of polymeric materials. The Agilent Cary 630 FTIR spectrometer offers unique features and class-leading performance, making quantitative analysis of polymers fast and easy. This application note focuses on the measurement of key components in two important copolymeric materials: the styrene content in styrene butadiene rubber (SBR) and the ratio of polyethylene to vinyl acetate in polyethylene vinyl acetate (PEVA) polymer. The Cary 630 FTIR, equipped with a single reflection Diamond ATR sampling accessory, is used for these measurements.

This application note demonstrates the analysis of Methyl Ethyl Sulfide (MES) in natural gas using the Agilent 490 Micro GC. The Agilent 490 Micro GC is a rugged, compact, laboratory-quality gas analysis platform that generates more data in less time for faster and better business decisions.

The GC analysis of four common polyunsaturated fatty acid methyl esters (PUFA FAMEs) in algal biodiesel is described using method EN 15779. An Agilent 7890A GC system was configured and calibrated according to the procedure outlined in the method. Two samples of B100 biodiesel made from algae oil were each prepared in duplicate and analyzed according to the conditions set forth in the method. In each sample, the four PUFA FAMEs were chromatographically separated and quantified. The analysis precision was calculated and shown to exceed the specifications of the EN 15779 methods.
