Here are Three Classic GC Problems... solved by CARLE Chromatography
PROBLEM 1 : HYDROGEN MIXTURES . . . measure hydrogen mixed with other gases and obtain high sensitivity, good linearity and positive peaks for all components. SOLUTION: The Hydrogen Transfer System. A significant breakt h r o u g h s u p e r i o r to any other chromatographic method. Found only on the new Carle AGC-111H. Practical for any sample type with hydrogen present, whether major or minor concentration. Here is the chromatographic evidence. For more, get the Carle HTS Bulletin. ™,-,r -.,
PROBLEM 2: TRACE CO . . . measure trace carbon monoxide in atmosphere with 2 ppm full scale s e n s i t i v i t y plus wide dynamic range. S O L U T I O N : The Carle Methanizer. The first completely reliable catalytic conversion of CO to methane fully integrated with a sensitive FID chromatograph. Found only on the new Carle AGC-211M. Here is the chromatographic evidence. For more, get the Carle Methanizer Bulletin. CIRCLE 23

PROBLEM 3: TRACE VINYL CHLORIDE . . . positively determ i n e if v i n y l c h l o r i d e is t h e volatile present in an industrial atmosphere. If it's there, simultaneously measure it accurately to less than one ppm. SOLUTION: The Carle 9500P. Overcomes the classic weakness of GC for qualitative analysis by innovative parallel column technique. Works equally well with other potentially t o x i c v a p o r s . P r i c e d at $1445. Here is c h r o m a t o g r a p h i c e v i dence. For more, get the Carle 9500P Bulletin. CIRCLE 24
