хроматограф(An explanation from a guy working in a lab: "I took an informal poll of the mass spec group in the lab next to mine, and most people use the term chromatograph to refer to the actual data – the peaks coming off the column. They refer to the instrument itself as the GC (for gas chromatography) or LC (for liquid). If they use a generic term, chromatography machine or unit is what is used" CopperKettle)
