4. Pulse Radiolysis Laboratory
Activity profile: Studies of charge and radical centres transfer processes in thioether model compounds
of biological relevance in liquid phase by means of time-resolved techniques (pulse radiolysis
and laser flash photolysis) and steady-state γ-radiolysis.
• Accelerator LAE 10 (nanosecond electron linear accelerator)
INCT (Warszawa, Poland)
Technical data: beam power – 0.2 kW, electron energy – 10 MeV, pulse duration – 7-10 ns and about 100
ns, repetition rate – 1, 12.5, 25 Hz and single pulse, pulse current – 0.5-1 A, year of installation 1999.
Application: Research in the field of pulse radiolysis.
• Gas chromatograph
GC-14B, Shimadzu (Japan)
Specifications: two detectors: thermal conductivity detectors (TCD) and flame ionization detector
(FID). Column oven enables installation of stainless steel columns, glass columns and capillary
columns. Range of temperature settings for column oven: room temperature to 399 o C (in 1 o C steps),
rate of temperature rise varies from 0 to 40 o C/min (in 0.1 o C steps). Dual injection port unit with two
lines for simultaneous installation of two columns.
Application: Multifunctional instrument for analysis of final products formed during radiolysis of
sulphur and porphyrin compounds and for analysis of gaseous products of catalytic reactions in
zeolites.
• Dionex DX500 chromatograph system
Dionex Corporation
Specifications: The ED40 electrochemical detector provides three major forms of electrochemical
detection: conductivity, DC amperometry and integrated and pulsed amperometry. The AD20 absorbance
detector is a dual-beam, variable wavelength photometer, full spectral capability is provided
by two light sources: a deuterium lamp for UV detection (from 190 nm) and a tungsten lamp
for VIS wavelength operation (up to 800 nm). The GP40 gradient pump with a delivery system
designed to blend and pump mixtures of up to four different mobile phases at precisely controlled
flow rates. The system can be adapted to a wide range of analytical needs by choice of the chromatography
columns: AS11 (anion exchange), CS14 (cation exchange) and AS1 (ion exclusion).
Application: The state-of-the-art analytical system for ion chromatography (IC) and high-performance
liquid chromatography (HPLC) applications. Analysis of final ionic and light-absorbed products
formed during radiolysis of sulphur compounds. The system and data acquisition are controlled
by a Pentium 100 PC computer.
• Digital storage oscilloscope
9354AL, LeCroy
Specifications: Bandwidth DC to 500 MHz; sample rate – 500 Ms/s up to 2 Gs/s (by combining 4
channels); acquisition memory – up to 8 Mpt with 2 Mpt per channel; time/div range – 1 ns/div to
1000 s/div; sensitivity – 2 mV/div to 5 V/div; fully variable, fully programmable via GPIB and RS-232C.
Application: Digital storage oscilloscope (DSO) with high speed and long memory controls pulse
radiolysis system dedicated to the nanosecond electron linear accelerator (LAE 10). The multiple
