RITA* radioactive TLC analyser

Applications

radioactivity detector for Thin-Layer Chromatography

β-  nuclides H-3, C-14 etc.

β+  nuclides F-18, C-11 etc.

external standardisation

ultra high sensitivity

General Description

RITA* - the radioactivity thin-layer chromatography detector - is using a linear analyser detector, which is sensitive over the entire chromatogram trace from the start to the front. The entrence window can be open for H-3 applications or closed for C-14 or any other beta- or beta+ radiation emitting nuclides. Many gamma radiation emitting nuclides are emitting beta radiation as well. The pure gamma emitting nuclides can be detected as well, because they produce some compton electrons.

RITA* has 2 simultaneous sensing electrodes: the delay line determines the location of the counted event, the pulse height of the counting wire is used for the electronic collimation. Thus high energy beta radiation can be detected with high resolution using a narrow collimator window.

RITA* can measure many single traces one after the other. The RITA* detector is elevated after the end of the measurement and moved automatically to the next trace position. Multi traces can be displayed in 3-dimensional presentation or a 2-dimensional distribution over the entire 200 × 200 mm. TLC plate can be calculated and presented.

Counting gas is a non-inflammable mixture of 90% Argon and 10% Methane, which is traded as P10 gas. The gas consumption is very low.

2 TLC plates of 200×200 mm each can be placed in RITA* at the same time.

A metal/glass cover closes RITA* completely and protects the environment as well as RITA* itself from electronic frequency emissions (CE).

Features

	open window detection for H-3
	antistatic protection grid for open window operation
	closed window detection for C-14, F-18, C-11 etc.
	very high sensitivity
	live-display of measurement
	peak integration, background subtraction
	manual or automatic
	limit of detection calculation

γ-miniGITA* γ-radioactivity TLC scanner

Applications

radioactivity TLC
radiochemical purity test

single trace TLC plate 50 × 200 mm

multiple nuclides

General Description

miniGITA* is a scanning device, which moves a radioactivity detector along 1 trace from start to front. The repeated, fast, continuous detection from start to front and back compensates automatically the radioactive decay of the compound over the scan length.

For γ-nuclides, miniGITA* is using a scintillation probe with a BGO crystal. Due to its density, BGO has aquite high stopping power for radiation and a reasonable energy resolution. BGO is mechanically quite stable and non hydroscopic. Relative small size and special shape enable a sophisticated design of the scintillation probe.

There are 5 mechanical collimators designed for the energy ranges of 0-60, 60-150, 150-250, 250-450, >450 in keV. Depending on the radiation energy of the radioactive compound, the suitable collimator is inserted into the detector. Simple, tools help to keep the distance exactly the same between the sample surface and detector entry window.

miniGITA* offers a calibration and sensitivity check. Inserting a suitable reference standard and running the calibration program will result in an energy spectrum scan and calibration.

After one scan the TLC plate can be moved manually to the following trace and the next TLC can be examined.

The chromatogram is displayed live on the screen of the connected PC. Peak integration and evaluation can be performed manually or automatically.

The measurement and data handing is digital (single event counting) and limit of detection can be determined for every small peak.

Features

	1 trace scan 25 × 200 mm
	automatic energy calibration
	extremely high counting rate
	dead time correction
	automatic decay correction
	I ve display on screen
	peak integration, TLC evaluation
	limit-of detection calculation

General Description

GITA* is scanning device, which moves the radioactivity detector along 1 trace from start to front and goes to the next pre-programmed trace position and scans that trace with individual nuclides settings.

For γ-nuclides, GITA* is using a scintillation probe with a BGO crystal. Due to its density, BGO has a quite high stopping power for radiation and a reasonable energy resolution. BGO is mechanically quite stable and non-hydroscopic. Relative small size and special shape enable a sophasticated design of the scintillation probe.

There are 5 mechanical collimators designed for the energy ranges of 0-60, 60-150, 150-250, 250-450, >450 keV. Depending on the radiation energy of the radioactive compound, the suitable collimator is inserted into the detector. Simple tools help to keep the distance exactly the same between the sample surface and detector entry window.

GITA* offers a calibration and sensitivity check by a reference source.

After all traces of 1 TLC plate 200 × 200 mm are ready, the second TLC-plate 200 × 200 mm can be scanned.

A single chromatogram can be displayed live on the screen of the connected PC. Multiple traces can be displayed 3-dimensional.

Peak integration and evaluation can be performed manually or automatically. The measurement and data handling is digital (single event counting) and limit of detection can be determined for every small peak.
