Precious Metal Dispersion Analyzer
Main Property
1. A variety of workflows- TPD, TPR, TPO, TPSR, Pulse Titration, Pretreatment and BET Specific Surface Area
2. Multiple Independent Gassource- In addition to carrier gas and reaction gas, each for independent control and mixes in scale.
3. Multiple Gas Joints - 3 for carrier gas and 3 for reaction gas
4. Steam Generator – It is equipped with a saturated steam generator and convenient to use reaction gas like liquid NH3.
5. Can be connected to GC or MS – It can be connected to the gas chromatography (GC) or mass spectroscopy (MS).
6. Auxiliary Detector – The instrument can output a voltage signal which is convenient to connect gas auxiliary detector, such as FID.
7. Material Structure - Stainless steel piping, seal for fluorine rubber, ask company for special custom if applied in special environment.
Precise Control
1. Flow Control – Using mass flow controller (MFC) software control, the flow is adjustable between 10 to 100sccm and software controls gas coefficient.
2. High Temperature Furnace – The highest temperature is 1000℃, and the stove heating rate can be adjustable from 1℃/min to 30℃/min.
3. Air Refrigeration – Open (shell type) furnace can be quickly cooling and optional refrigerator achieving rapid refrigeration.
4. Optional Cryotrap – The temperature can be rising from -100℃.
5. Temperature Control – Piping, steam generator, stove and TCD temperature can all be controlled by digit.
6. Thermal Conductivity Cell Detector – 4-arm rhenium tungsten TCD has extremely high linear, accuracy, sensitivity and stability.
7. Very small dead volume - Small volume valve and 3 mm pipe can reduce dead volume, thus reduce the deviation of the peak.
Easy Operation
1. Sample Support – U type pipe of large size can be convenient for sample loading and cleaning, and can add powder, rod or shot sample.
2. Sample Loading – Sample tube free of taking down is convenient to load samples.
Safety
1. Heating Pipeline – All the pipeline, valve and liquid carburetor are heated to prevent condensation.
2. Safety – Independent furnace temperature thermal protection, sealing pressure reducing valve, current circuit breaker, fuse, the system design has timely security protection.
