Latest issue of company magazine identifies four main culprits that shorten gas chromatography column life, and discusses the importance of sample cleanliness
Agilent Technologies Europe reports that the latest edition of Separation Times, Vol 15, No 2 (publication number 5988-7353ENE), examines gas chromatography (GC) column longevity.
A feature article explains the conditions that affect column longevity and compares Agilent column lifetimes - as well as column bleed - with two other manufacturers'.
Separation Times' regular article 'Ask Technical Support' isolates the four main culprits that shorten column life.
Also covered is a major component of column longevity - sample cleanliness.
The magazine explains how to improve sample cleanup with solid phase extraction (SPE) vacuum processing.
Another influence on column life is septa quality.
Chromatograms comparing septa with that of three other manufacturers reveal the significant difference that septa quality can have on column life span and bleed.
In another article, separate trace analyses of chromatographically active compounds reveal the importance of column quality on inertness and column bleed.
This study compares the Agilent HP-5 column with equivalent columns from two other manufacturers.
This issue of Separation Times also initiates a series of articles on how to access Agilent's considerable chromatography resources online.
The first installment demonstrates, through screen captures, how to find and download information-packed technical publications and brochures.
