Description Of Products
-AA-1800DL
AA-1800DL Series are Single Beam Atomic Absorption Spectrometers controlled and data processed by external computer and internal CPU chips.
AA-1800DL can be used to measure the concentration of macro, micro and trace metal elements and half-metal elements in various kinds of substances. AA-1800DL is provided with three reading methods Continuum, Retention and Peak Height for measuring absorbency, density and emission intensity. It has three signal modes: Atomic Absorption, Background Absorption and Background Correction Absorption. AA-1800DL include 8 computer controllable hollow cathode lamp holders. All working conditions of the instrument such as lamp current, negative high voltage, working wavelength, auto gaining, background correction, automatic energy balance, optional lamp holder, slit, wavelength scan, auto peak location, auto ignition/extinction, acetylene flow demonstration/control and atomizer location adjustment can be realized through software control. All the readings, measurement results, calibration curves and operation conditions can be saved or printed out. The instrument provides 1-9 standard density calibrations; slope can be adjusted by single standard sample; the functions are as linear regression, curve fitting, linearity and non-linearity addition method measurement, average and precision calculation. The instrument can be linked with computer for controlling and data processing. This instrument confor
