1、 Product Description:
The 361CRT/361MC atomic absorption spectrophotometer is a new generation of intelligent and popular instrument. Its performance is very stable, and the powerful microcomputer data processing function can instantly complete operations. It is actually a powerful tool for material analysis and quality control departments in industries such as metallurgy, geological environmental protection, food, medical, chemical, agriculture and forestry to conduct constant and trace metal (semi metal) element analysis. It is one of the essential conventional instruments for analytical laboratories in production, education, and scientific research units. Among them, 361MC is a microcomputer instrument, and 361CRT is an external PC slim data station based on the host (MC type).
2、 Characteristics:
1. Rich functions: The computer automatically deducts blank values, sensitivity drift, baseline drift, calculates mean and deviation, calculates working curve equations and reads concentration values, prints analysis reports, and can also perform flame emission spectrophotometry, hydride generation atomic absorption spectrometry, and online enrichment flow injection atomic absorption spectrometry analysis.
2. Easy to operate: After setting the conditions, simply press the button twice each time to automatically read/print out the absorbance value, concentration value, and relative standard deviation. Compared with non microcomputer instruments, it saves a lot of manual data processing time.
3. Signal stability: Adopting imported high-quality photomultiplier tubes and advanced integrated circuits, single beam optical path, strong light monochromator and high-efficiency atomizer, ensuring strong energy, low noise, and good accuracy across the entire wavelength range. The computer logarithmic transformation is accurate, without temperature drift, and has good baseline stability.
4. Peak finding precision: The specially designed wavelength fine-tuning mechanism can accurately align the peak position of the wavelength.
5. Continuous slit: The unique continuous slit mechanism ensures extremely high resolution and optimal spectral bandwidth.
