“Translations Between Differing Liquid Chromatography Formats: Advantages, Principles, and Possible Pitfalls”

Un-beknown or perhaps exploitation by Column OEMs > ignorance ( or just the usual marketing practice ? ) coarse > fine particles ( 1.8um vs 5um); Solid core > “New” Porous-Shell column material > all necessitates the practical determination HPLC > micro-HPLC ( uHPLC ) |
GC Column Oven Temperature for those actually ”Smart Enough(?)”
> a neglect / oversight of ALL GC OEMs
|
NO GC OEM bothers to calibrate THIS Is essential as RI does depend

Often to meet QC specs analysts mave have a tendency to allow column instrument performance to deteriorate >by simple attrition OR Not even monitor |
