VARIAN MAT - the leading name in mass spectrometry and MS data systems

When others can't even find it, we can still identify it.

Food Research e.g. -Fusel oil fraction in alcoholic

beverage samples -Chloroanisoles in tobacco

Drug analysis e.g.-Barbiturates: phenobarbital in

rat urine -Morphine

Biochemistry e.g.-Prostaglandins:

PGF2 a -derivative

Pesticide analysis e.g. -Aldrin, dieldrin, endrin, DDE, DDT,

heptachlor -PCBs

Clinical chemistry Organic chemistry e.g. -Catecholamines: a -methyl-3- e.g. -Octa-and nonabromobiphenyl,

methoxytyramine direct insertion -Steroid derivatives: testosterone, -Phosphonitrilic chlorides, direct epitestosterone, cholesterol insertion acetates in urine;TMS derivatives.

Analysis of trace amounts? No more than a routine operation for the MAT 112 GC/MS system (100pg for complete spectra; a few pg by the MIS process).

What this new system can do for you is detailed in the information package MAT 112/1.

We would be pleased to send you one.
