Agilent Manuals

The advantages of automating sample derivatization are presented, including increased productivity and reduced cost. Examples of sample derivatization with fatty acids, pentachlorophenol, and morphine are provided. Silylation derivatization of fatty acids improves peak shape and resolution.

Varian's Bond Elut Plexa solid phase extraction (SPE) column has a very high extraction capacity for analytes and efficient removal of contaminants, making it ideal for extraction of phenols from drinking water.

Agilent Bravo is an automated liquid handling platform that has nine deck positions that can be configured with interchangeable 8-, 16-, 96-, or 384-fixed and disposable tip heads. The platform has excellent accuracy and precision and can be used in a variety of laboratory applications.

This document introduces the enhanced separation power of GC x GC, which can be combined with selective and non-selective detectors to provide enhanced sample information and confirmation that would otherwise not be possible in a single run.

This document describes some of the lessons learned from using a flow modulator to modulate methane and points out some common erroneous assumptions, such as that stationary phase bleed is a good indicator of hold-up time. When using this approach to perform fundamental retention studies, one cannot escape the fundamental pitfalls of capillary chromatography. Loss of He through fused-silica at high temperatures and low flows can cause significant errors.

This document introduces the market situation of ethanol fuels made from renewable biomass worldwide, as well as the key feedstock and specifications requirements for ethanol fuels. By using multidimensional capillary column GC (MDGC) system, multiple individual measurements can be combined into a single run, greatly reducing the analysis time.

Introduction to Easy SamplePrep Add-On Software, which provides simple and easy-to-use automated sample preparation for 7693 ALS and Tray, including derivatization, internal standard addition, serial dilution, heating, cooling, mixing, etc.

Introduces the method of using Agilent PLgel 10 µm MIXED-B columns to analyze fluoropolymers

This document introduces the effective method for analyzing butyl rubber with Agilent PLgel 10 µm MIXED-B columns.

Agilent PLgel 5 µm MIXED-C Columns are designed for rapid polymer analysis. With its linear calibration up to 2 million MW, this is the column of choice for highest resolution and accuracy in molecular weight distribution analyses.

This document provides a technical overview of Agilent PLgel 5 µm MIXED-C Columns GPC calibrations and hydrodynamic volume. When calibrating the same column with standards of different chemical composition, the shape of the calibration should be similar. The plots will differ according to the hydrodynamic volume of each polymer in the element used.

The PLgel 5 µm MIXED-C columns are designed for rapid polymer analysis and are ideal for comparing batches of polycarbonate. With its linear calibration up to 2 million MW, PLgel 5 µm MIXED-C is the column of choice for highest resolution and accuracy in molecular weight distribution analyses.

This document introduces the technical overview of Agilent PLgel 5 µm MIXED-C columns, including the adsorption phenomena in organic GPC separations and how to minimize this impact by modifying the eluent polarity.

This document describes the use of Varian CP-4900 Micro GC and provides an example of how to use the EDU-Varian Sample Concentrator to concentrate samples to improve the detection limit.
