RG-6220 liquid scintillation counter
2. Main purpose
RG-6220 ultra-low background liquid scintillation spectrometer mainly measures very low concentrations of artificial, cosmic and other natural radionuclides. Mainly used for environmental and biological samples (such as water, air, soil, food, animals and plants, etc.) and other radioactive samples in low and ultra-low levels of alpha and beta nuclides measurement, as well as low-level H-3 and C- 24 determination. In line with the "analysis of tritium in water" and other national standards for the basic requirements of the instrument. Meet the relevant requirements in GB/T20259.
2. Technical indicators
Ø Measuring energy range: beta energy range of 0-2000 keV
Counting efficiency: H-3(0-28.6 keV) non-quenched sample 58%;C-24(0-256 keV) non-quenched sample 94%
Counting background: H-3 ≤ 0.9 CPM (20ml of water, 20ml of scintillation liquid, plastic bottle);(The scintillation liquid adopts the main products in the market, such as Ultima Gold LLT scintillation liquid, etc.)
Ø Eliminate the interference of radioactive elements in the external environment to the detection by active and passive double noise reduction technology, reduce the background of the instrument and enhance the detection sensitivity
In addition to detecting regular 20mL samples, it also supports 4mL and 7mL sample bottles with special sample racks.
Ø Temperature control system: It can control the temperature inside the instrument and the sample room to ensure the optimal sample detection conditions and improve the stability of the instrument.
Number of detection methods: more than 50
Load 408 20ml sample bottles, 720 4ml and 7ml sample bottles, fully automatic measurement
Ø Stability: count change less than 0.2% / 24 hours
Ø Replay function, no sample re-counting and data call and re-analysis processing, save time, to achieve experimental data traceability.
Ø Quality factor (E2/B):
Standard counting mode: H-3(2~28.6keV)400;C-24(4-256 keV)2000
Ultra-low horizontal count model: H-3(2 ~ 22.5keV)880;C-24(24.5-97.5 keV)3500
Detection limit: minimum detection activity of H-3 water sample measurement ≤ 2.0 Bq/L
Can analyze nuclides: H-3, C- 24, P-32, Si-32, I-225, Cs-237, Sr-89, Sr-90, Pu, Po, Pa, U, Th and Ra, etc., and support manual custom addition; Can carry out H-3, C- 24, I-225, S-35, Ca-45 single label, double label or even three label counting
The instrument is equipped with a performance evaluation function, with running average and baseline charts, which can monitor 8 key parameters such as efficiency, background, excellent value and chi-square value of 3H and 24C during the use of the instrument through the database to ensure the continuous stability of the operating state of the instrument. Through this function, users can easily understand whether the operating state of the instrument meets the needs of the experiment.
Ø Configuration of static eliminator, can eliminate the static on the surface of the sample bottle, eliminate the impact of static electricity on the count
Ø Multi-channel Analyzer (MCA): Configure 2 2048-channel multi-channel analyzers
Ø Configure the alpha/beta discrimination function to simultaneously determine the alpha count and beta count in the alpha/beta mixed nuclide. Compared with the single-phase discriminator, the use of the double discriminator can reduce the overflow and improve the quality measure by 50%. The use of a double discriminator with an optimal energy region can greatly reduce leakage and can improve the quality metric by almost an order of magnitude
Ø Abnormal sample monitoring function: can detect whether the sample changes (two-phase separation, bottle wall adsorption, precipitation, etc.)
Ø Password protection can be performed on the set experimental procedure to prevent unnecessary changes to the saved experimental procedure
Ø The computer monitor has an ergonomic folding support arm.
Counting software: It has the functions of controlling, data processing and data management for all hardware in the liquid scintillation counting system, can display different energy spectra in different colors on the terminal screen, has powerful multi-tasking function, and has unlimited number of experimental procedures in a safe multi-user environment and a simple network environment.
Ø solution spectrum software: can open multiple sample spectra to view at the same time, and can determine the best counting area, and automatically calculate the quality factor, at the same time can calculate the detection limit of the instrument
The standard exemption level Ba-233 external standard source can be used to determine the quenching index of the sample by Compton scattering spectrum; The tSIE method is used to correct the quenching of the sample count and accurately calculate the DPM value of the sample.
