The new Generation II Protein 230 assay offers an extended sizing range from 14 to 230 kDa.

The document introduces the asset management and service reporting functions of Agilent Lab Resource Management (LRM), including asset detailed registry, service history information, asset reliability and service delivery performance reports.

This document introduces the performance of the Agilent 1200 Series diode-array detector (DAD) using different detector cells and different data rates up to 80 Hz.

This document introduces how to use elevated temperatures to improve the speed, resolution and peak shape of the Agilent 1200 Series Rapid Resolution LC system in LC applications

This Technical Note evaluates the precision of retention times for gradient and isocratic applications, and demonstrates that linear and stepwise gradients are delivered with excellent accuracy and precision.

Introduces the design of the Agilent 1200 Series column compartment and the influence of the new design on dispersion and detector noise.

This document describes the features and performance of the Agilent 1200 Series high performance autosampler SL. The autosampler is based on a flow-through design, allowing for precise injections and linearity over a wide injection volume range. Additionally, it offers a low minimum accessible volume and minimal carry-over. The document also evaluates the area precision for fast gradient and isocratic applications.

The paper introduces SemiQuant method, which is used for preliminary identification of unknown compounds based on mass spectral features, retention time and chemical criteria such as sample extraction and processing. The method can be used to estimate the concentrations of various similar compounds.

Agilent's non-stick O-rings are used to improve GC inlet maintenance, using non-stick O-rings can improve performance and reduce maintenance time

Choosing the right injection port septum for your GC is not as simple as picking up any supplier’s catalog, looking at the temperature range stated for the septum, and assuming that it is made to the same specifications as any other septum. While it is true that there are a limited number of manufacturers of GC injection port septa, the specifications that are applied to one retail supplier are more likely not going to meet the same specifications of another. It would be true to say that only the design engineers of the specific GC’s injection port will know what specifications are needed for the best operation of the inlet as its intended design. Among other criteria, the septum must be of the correct dimensions and elastic density to cause sealing of the injection port in order to allow high-pressure carrier gas to be channeled to the GC column without allowing leaks. It must also do this in such a way to allow a relatively fragile syringe needle to pierce the disk in order to inject a sample into the inlet liner. While the disk is pierced with the needle, it must maintain a seal around the needle until it is eventually removed from the septum, and then the septum must be pliable enough to seal itself off to prevent the vaporous sample from escaping out through the needle’s hole. This self-occluding characteristic is absolutely vital in order to prevent the diffusion of air (containing oxygen) into the inlet. Allowing air into the carrier gas through insid

This document describes the design characteristics of the ferrules used in GC instruments and their contribution to chromatographic signal noise. It also mentions the impact of residue on the background signal during column installation.

This document describes how to build and edit RTL Screener databases, RTL Quant databases, and Mass Spectral Libraries using the GC/MSD ChemStation software and Microsoft Excel.
