gas chromatographic flame photometric detector analyzer

GC-FPD analyzer

Disclosed is a method for photometrically detecting the presence of a given nucleic acid sequence after amplification by the polymerase chain reaction (PCR).

The amino acids are separated by ion exchange chromatography and determined by reaction with ninhydrin with photometric detection at 570 nm.

ion exchange chromatography coupled with post-column derivatisation and photometric detection (IEC-UV/FD) – EN ISO 17180 or VDLUFA 4.11.6 and EN ISO 13903

The system includes a sealed non-intrusive sample cuvette, a housing with an enclosable cover, systems for incubation and photometric detection mounted within the housing.

The amino acids are separated by ion exchange chromatography and determined by reaction with ninhydrin using photometric detection at 570 nm (440 nm for proline).

A sample (101) of a patient's serum or the like is pretreated with an immunological pretreatment device (103), and then subjected to photometry with an immunological photometric detection system (104).

The invention relates to an analysis system for the photometric determination of an analyte in a body fluid, having an analysis device (2) and a test carrier (3).

The ST-COD method is based on exactly the same reaction as described in the classical method, but instead of titration, a photometric detection is used.

EN ISO 15682:2001 Water quality – Determination of chloride by flow analysis (CFA and FIA) and photometric or potentiometric detection (ISO 15682:2000)

Using both single-count and photometric detection modes, it provides highly accurate measurements for concentrations as high as 107particles/cm3.
