Which generator is good

1.1 This type of hydride generator belongs to the flow injection type,Must be connected to an atomic absorption spectrophotometer(host)use in combination,Determination of arsenic, selenium, antimony, bismuth, lead in samples by hydride atomic absorption spectrometry Tin Determination of mercury by tellurium and cold atomic absorption method.

1.2 Work situation: Using carrier gas pressure and electronic components as automation energy sources,Press the start button,Automatic quantitative inhalation3 Seed solution (boron hydrogen potassium oxide, sample, carrier solution),Send a reading signal after filling up,The carrier solution carrying the sample and the boron hydride potassium solution begin to flow steadily,After merging, a reaction occurs and the product is carried into the gas-liquid separation tube by the carrier gas,The mixed gas enters the electric quartz absorption tube atomizer for atomization absorption, and the waste liquid is automatically discharged. The original absorption host software is set to read the "peak height" (or peak area) and the integration time15~40s（ The reading time required varies depending on the atomic absorption spectrometer of different manufacturers.

1.3 The advantages of this series of generators:

⑴. *Wu's pneumatic automation expertise includes automatic liquid inlet technology(Replace peristaltic pump)The system, liquid measurement system (quantitative injection), independent multi-channel switch air resistance, stabilizer breathing tube, etc. are automated systems that use the pressure of the carrier gas source and electronic components to work. The electronic program - time controller, etc. are all exquisitely installed,Better performance than fully electric automation systems.

⑵. High degree of automation: With just one start button, the entire process of sample injection, generation, measurement, and cleaning can be completed with a light press. It can be connected to the host for automatic reading (the host must have this function).

⑶. *Electric quartz absorption tube (atomizer): compact device(*Can be used for absorption tubes on Zeeman type hosts)Rapid heating up,Easy installation, stable temperature, adjustable freely, longer service life than flame heating10More than double,Eliminating fuel consumption, the analysis method can be quickly changed as long as the temperature drops. New material safety protection cover, sturdy and reliable.

⑷. performance analysis(Sensitivity, detection limit, stability, and work efficiency)*Sensitivity, most measurable hydride elements are better than1ng/mL/1%AFor example, arsenic is superior to0.15ng/mL/1%ARelative standard deviation(RSD)Factory control indicators are less than3%The duration of a single measurement is approximately25-35In seconds.

⑸. Strong adaptability: All domestic and foreign new and old models of atomic absorption hosts can be used.

⑹. High reliability: Low failure rate, with almost no vulnerable parts.

⑺. Lightweight and compact: Net weight of approximately 2.5kg,long250mm, Wide175mm, highm190m.

⑻. Multiple reading methods are applicable: peak height reading (using this method),Peak area reading, continuous reading.

⑼. Low solution usage - sample solution1-2.5mL(Including cleaning)；硼-氢-化-钾溶液1-1.5mL; Carrier liquid4-7mL.
