for the BEST
in
Gas Chromatography Quite S i m p l y . . . Your gas chromatograph is not capable of giving you the very best in gas chromatographic analysis unless it is equipped with capillary columns. W h y . . . Consider these advantages of capillary c o l u m n s : •
Resolutions which are impossible on packed columns.
•
Analyze very small samples with ionization detector systems.
•
Temperature programming extends the range of capillary columns, simultaneously providing excellent resolution and high sensitivity to report trace constituents in extremely complex mixtures.
•
Better resolution of complex samples with very similar structural groups.
•
A complete analysis in 20 minutes which may take more than an hour with packed columns.
•
Analyses which require temperature programming with packed columns can normally be performed isothermally with capillary columns.
Also of Prime Importance . . . Barber-Coiman has been a leader in t h e manufacture of capillary columns and capillary column gas chromatographs for many years. The excellent capillary runs on the preceding page are examples of the performance obtained with Barber-Coiman capillaries. Remember — " T h e Chromatogram Is The Proof." Y o u Should Also K n o w that . . . The Barber-Coiman Series 5000 Selecta-System Gas Chromatographs were designed for capillary column systems and they feature:
The Barber-Coiman Series 5000 Selecta-System represents a most flexible system for keeping abreast of a fast-changing technology. The modular unitized system fits your needs now and later — over 20 different components help to make up more than 50 different system combinations.
