TA - Model SSS-12P-1/SSS-22P & SSS-22-PAL -Portable Liquid Scintillation Counting System
The SSS-12P Manual Liquid Scintillation Counting System accurately quantitatively measures Carbon-14, Tritium and most other radioactive materials. But for measuring low levels of Tritium and C-14, Model # SSS-22P is recommended. Optionally, gamma ray counting is achieved by inserting and optically coupling an Nal(Tl) scintillation well crystal on the PM tube.

- Measuring Principal: The most sensitive method of detecting and quantitating Beta emitting isotopes is to intimately mix the sample with liquid scintillation fluor and count each individual scintillation event with a photomultplier counter.
- Alpha / Beta Separation.
- Count Verification for Tritium.
- An Energy Analyzer further selects the pulses and delivers the true signal.
- A Detection cell is optically coupled to selected photomultiplier tubes.
- SSS-12P-1 has a 1 Vial Capacity – 1 PM Tube.
- SSS-22P has a 3 Vial Capacity providing faster thru-put and easy comparison of sample to calibration standard or to background – 2 PM Tubes
- SSS-22PAL has a 3 Vial Capacity as does the SSS-22P providing faster thru-put and easy comparison of sample to calibration standard or to background. It is an ALL-IN-ONE SSS-22P contained within a suitcase with electronics, detectors, and sample holders for your convenience.
- A User Manual is provided.
- Measures all alpha - beta emitters and low energy gamma emitters – including
- Tritium, carbon-14, & sulphur-35
- Alpha / beta separation
- Dual pm tube design for coincidence verification
- Sss-12p-1 – single sample holder
- Sss-22p – three sample holder
- Settable window can be set for any isotope
- Sample type: water, food, soil, fabric, etc.
- All in one unit– sss-22-pal
- R-232 pc interface
- Optional - hard copy printer
- A Liquid Scintillation Counting System is useful for measurement of radionuclides in many materials including food, soil, water, blood, etc.
- The SSS-12P-1 & SSS-22P Manual Liquid Scintillation Counting Systems accurately quantitatively measures Carbon-14 and most other radioactive materials.
- The SSS-22P also measures Tritium & Exceptional for measuring low levels of Tritium, C-14, & S-35.
Rejection Features:
- Energy analyzer window rejects pulses with energies outside the window setting
- Optional Lead Shielding around detector.
Counting Assembly Features:
- Excellent repeatability
- Fully light tight system
- Fail safe interlock to protect PM tubes
- High transmission optical coupling to PM tube
PM Tube & PRE-AMP Noise Elimination Features:
- Coincidence Verification with High quality Dual PM tubes and preamps.
- Fully adjustable energy analyzer window rejects low energy pulses.
- SSS-12P-1: 1 Vial Capacity – 1 PM Tube.
- SSS-22P: 3 Vial capacity for faster thru-put and easy comparison of sample to calibration standard or to the background – 2 PM Tubes
- SSS-22P: 3 Vial capacity provides less wait time for dark adaption of phosphor.
Data Analysis & Presentation:
- Scintillation counts detected by PM tubes are processed by a fully adjustable single channel analyzer which is
- centered on the energy peak of the isotope being measured. This deletes both higher energy pulses from background
- radiation and lower energy counts from the PM tube or circuit noise. The pulses feed to a digital scaler and optional
- digital printer.
- This process allows long count times for measurement of very minute samples.
- USB interface to computers or data stations.
- H-3 Gross Efficiency: >20% Gross, Coincidence efficiency >10% Verified.
- Count Times: 1 sec. thru 99 sec. (1 sec. increments), and 1 min. thru 99 min. (in 1 min. increments).
- Voltage: 0-1500 Volts - fully user settable.
- Readout: Digital - 6 digit LCD, (LED optional).
- Outputs: Standard: Serial pulse output and R-232.
- Power: Rechargeable Lithium batteries and AC adapter
- Sample Size: Accepts standard Liquid Scintillation vials 20-25 ml.
- SSS-22 PAL Case: Weather-tight NEMA rated tough, durable, lightweight.
- A “tongue-in-groove” continuous O”-ring system makes the case water, moisture, and dust tight. Plus a low profile pressure release valve.
- Optional:SSS-22P: Accepts 6-7 ml vials with Optional adapter.
- Scintillation Fluors: Accepts most scintillation fluors. Perkin-Elmer Ultima Gold-LLT is recommended for H-3 counting
- Set of 3 calibrated liquid standards, H-3, C-14 and S-35. User must mix TA solutions with liquid scintillant.
