Recently, the General Administration of Customs has successively issued the announcement of the procurement project of special instruments in 2024, and the total amount of the procurement budget issued has reached 87.33 million yuan, involving a total of 135 instruments such as gas chromatograph, liquid chromatograph, mass spectrometry, atomic absorption spectrophotometer, etc., East-West analysis can provide corresponding instruments, among which, AA-7090 atomic absorption spectrometer was rated as "domestic good instrument", participated in the support of the Beijing Municipal Science and Technology Commission, China Customs Science and Technology Research Center (formerly Beijing Entry-Exit Quarantine and Inspection Bureau) organized the sixth "domestic testing equipment verification and comprehensive evaluation" project, and achieved satisfactory results.
East-West Analysis Product Solution Introduction
Atomic Absorption Spectrometer, Solutions
The East-West Analysis AA-7050 and AA-7090 atomic absorption spectrophotometers have participated in the "Verification and Comprehensive Evaluation of Domestic Testing Instruments and Equipment" project organized by the China Customs Science and Technology Research Center. In the project, the laboratory evaluated the basic performance indicators of the instrument such as baseline noise and drift, detection limit, repeatability, linear error, minimum resolution of the instrument, etc., and the performance indicators of the instrument methodology. It was determined that these two atomic absorption spectrophotometers are the first choice for heavy metal analysis.

AA-7090 at Work (Evaluation Laboratory)
Evaluation of the instrument by the China Customs Science and Technology Research Center: Atomic Absorption Spectrophotometer AA-7090 has further improved the performance of the instrument and expanded the application field on the basis of AA-7050, and can be applied to metallurgy, petrochemical, geology, medicine, environmental protection, scientific research, agriculture (soil and fertilizer), disease control, food, material science, commodity inspection, etc. The basic performance indicators of the instrument were verified from two aspects, including the baseline noise and drift of the instrument, detection limit, repeatability, linear error, instrument background correction ability, instrument minimum resolution and other basic performance indicators. The instrument methodological performance indicators refer to the "JJG 694-2009 Atomic Absorption Spectrophotometer Verification Procedures", and use environmental standard samples BY400039 standard lead and GBW10025 spirulina composition analysis standard materials for verification. Its instrument repeatability, short-term stability, long-term stability and accuracy can meet the requirements of laboratory testing and scientific research. It is the first choice for heavy metal analysis.
