Overview

The switching of flame graphite furnace atomizers is convenient and fast. The $r $n optical platform is cast as a whole, with good seismic resistance and a more stable optical system. $r $n has low light energy loss and high sensitivity. The $r $n adopts a full band high-resolution symmetrical aberration cancelling Czerny Turner monochromator, which provides more accurate wavelength positioning. The $r $n4 lamp position automatically rotates and switches, supports cathode lamp preheating function, and optimizes working conditions. The concentration calibration of $r $n1~30 point standard can be performed with a single standard sample for slope adjustment. Equipped with functions such as linear fitting, curve fitting, and automatic calculation of mean and relative standard deviation using linear and nonlinear standard addition methods

Software functions:

Concentration calculation method: Standard curve method (single point calibration or multi-point calibration, multi-point calibration can choose 1st, 2nd, 3rd order functions and convert to each other) or standard addition method for testing, with a maximum of 20 repetitions, automatically calculating the mean, standard deviation (SD), relative standard deviation (RSD) and other functions.

Sample information table editing and data processing function: Provides sample information editing such as weight factor, volume factor, dilution factor, etc., which can directly calculate the actual sample concentration (sample content) and improve the completeness of experimental reports.
