In terms of detection sensitivity, the instrument also performs well. Characteristic concentration when analyzing copper element using flame method<0.04μg/mL/1%The detection limit is as low as0.006μg/mLWhen analyzing cadmium element using graphite furnace method, characteristic quantities<0.5×10 ⁻¹²gThe detection limit is up to1.0×10 ⁻¹²gPrecisionRSD≤3%Can meet the stringent requirements of trace element analysis.

Innovative product features to enhance analytical efficiency

Design of Horizontal Heating Graphite Furnace

TAS-990GAtomic absorption spectrophotometerBy using transverse heating graphite furnace technology and optimizing the heating method of graphite tubes, the uniform distribution of temperature field has been achieved. This design effectively reduces chemical interference and memory effects, not only improving atomization efficiency, but also extending the service life of graphite tubes, ensuring the accuracy and repeatability of analysis results.

Highly automated and intelligent

The instrument is equipped with powerful functionsAAWin2.0Analysis assistant software, supporting automatic switching of eight lamp turret, can pre-set and optimize the working conditions of hollow cathode lamps, achieving rapid detection of multiple elements. The functions of automatic flow setting, automatic ignition and shutdown protection, automatic adjustment of negative high voltage and lamp current greatly simplify the operation process. At the same time, the software supports various concentration calculation methods such as standard curve method, standard addition method, and interpolation method, and has functions such as automatic fitting of standard curves, dynamic display of measurement data, and generation of analysis reports, which enhance the intelligence level of data analysis.

Reliable security protection system

TAS-990GAtomic absorption spectrophotometerAdopting multiple safety protection designs, including flame monitors, acetylene leak alarms, abnormal pressure monitoring, and other functions. In the process of flame analysis, if an unexpected power outage or operational error causes the flame to extinguish, the acetylene gas path will immediately shut down automatically and sound an alarm; During graphite furnace analysis, the system will monitor the pressure of the protective gas and the flow rate of the cooling water in real time. If any abnormalities occur, heating will be stopped immediately to ensure the safety of operators and equipment.

Excellent scalability

The instrument supports expansion modules such as flame automatic sampler, graphite furnace automatic sampler, hydride generator, etc., which can easily meet diverse and complex analysis needs. Whether it is large-scale sample screening or high-precision trace analysis,TAS-990GWe can provide flexible and reliable solutions.
