Agilent Micro Liquid-Liquid Extraction with the Agilent 7683 Automatic Liquid Sampler
Agilent Optimized Determination of C1-C6 Impurities in Propylene Ethylene Using HP-PLOT/Al2O3 Columns
This article introduces the method of optimizing determination of C1-C6 impurities in propylene and ethylene using HP-PLOT/Al2O3 columns. Compared with other commercially available alumina PLOT columns, HP-PLOT columns have better selectivity, increased capacity and complete baseline separation. HP-PLOT column analyses were done using the 5890 Series II gas chromatograph with electronic pressure control and a flame ionization detector.
Agilent Mass-based fraction collection of synthetic peptides using the Agilent 1100 Series purification system
This Application Note demonstrates mass-based purification of a series of synthetic peptides with the Agilent 1100 Series purification system. The modular set-up of the system, a reliable fully-automated delay volume calibration and a comprehensive software package provide a versatile platform for purification tasks up to 100 mL/min. Crude peptides were successfully purified by reverse phase HPLC from less than 1 kDa to more than 10 kDa, covering a pI range from 4 to 13.

Agilent The Agilent 1100 Series high throughput system - instrumentation software applications
Agilent 1100 Series high throughput system introduction
Agilent Development of a compound purification strategy for a medicinal chemistry group
A purification strategy for a medicinal chemistry group at Boehringer Ingelheim in Vienna, Austria, using the Agilent 1100 Series purification system was developed. The goal was to develop a simple purification process, which could be easily used by all chemists. Further challenges were to develop a set of pre-defined methods to purify not only simple samples but also problematic samples, such as insoluble samples, polar samples and samples that show poor ionization.
Agilent Handling of Electronic Records with ChemStation Plus
This document describes the nature and location of all electronic data in a ChemStation Plus networked data system, including the add-on modules ChemStore as central database and Security Pack for support of compliance requirements. The document will help system and laboratory managers to understand how electronic results are managed by a ChemStation Plus system and how all related records are linked to a final result. The document will also help system administrators to understand the format of all ChemStation Plus electronic data, the data location and data organization in the database, and the operating system perspective. The ultimate goal of this document is to give every system user an outline of the ChemStation Plus structure, which will allow them to prove data integrity of their results and of the entire system during an audit or investigation. This document should be stored and managed carefully as the information contained herein could be misused to modify or manipulate ChemStation Plus electronic records.
