HP 6890 Gas Chromatography GC system
EUROPE (Western and Northern)
as Chromatography GC system with FPD dete
The Agilent 6890 GC (Gas Chromatography) System, somet
imes referred to as the HP 6890, is the powerful successor
to the HP gas chromatograph series.
It is considered one of the best gas chromatography systems available today,
providing excellent results for a wide range of research laboratory applications,
including hydrocarbon processing, food safety,
pesticide determination, chemical analysis, biodiesel,
drug screening, toxicology, environmental and law enforcement.
Flame Photometric Detector (FPD).
The flame photometric detector (FPD) enables sensitive
and selective measurements of volatile sulfur and phosphorus compounds.
The detection principle is based on the formation of excited sulfur (S2*)
and excited hydrogen phosphorus oxide species (HPO*)
in a reducing flame. A photomultiplier tube measures
the characteristic chemiluminescent emission of this species.
The optical filter can be changed to allow the photomultiplier
to detect light at 394 nm for sulfur measurement or 526 nm
for phosphorus measurement.
The detector response to phosphorus is linear,
while the response to sulfur depends squarely on concentration.
