Analytical instrumentation, necessary to analyze for the typically low product concentrations in radiation and photochemical experiments, includes the state-of-the-art DX500 Dionex (USA) system for IC and HPLC applications. The system consists of: ED40 electrochemical detector with conductivity detection, DC amperometric detection and integrated and pulse amperometric detection (automatic compensation of the background circuit is possible), AD20 absorbance detector with wavelength range 190 to 800 nm, GP40 gradient pump with delivery system designed to blend and pump mixtures of up to four different mobile phases at precisely controlled flow rates, AS11 (anion exchange), CS14 (cation exchange), AS1 (ion exclusion) chromatography columns. The system can be adapted to a wide range of analytical needs by choice of columns, eluent compositions and flow rates. The system and data acquisition are controlled by PC computer.

The GC-14B gas chromatograph is a multipurpose instrument exhibiting high-performance. This GC unit has small installation area requirements and large system expansion capabilities.
Two detectors are installed in the chromatograph: thermal conductivity detector (TCD) and flame ionization detector (FID). Column oven enables installation of stainless steel columns, glass columns and capillary columns. Range of temperature settings is from the room temperature to ~399ºC (in 1ºC steps), rate of the temperature rise is from 0 to 40ºC/min (in 0.1ºC steps).
GC-14B has a dual injection port unit with two lines for simultaneous installation of two columns.
