Take samples, the surface of the single product that has not been cut must be larger than 1m, and the sample must be cut to ensure that the sample is not less than 1m thick and the sample is not more than 2 pieces. The sample must be clean and level. The equipment must be milled with a machine frame, sand and milk machine or belt machine. The standard product and the product seat must not fall off under the company's conditions. Note: The service material can not bring any impact on the flow of the relevant materials. 6 Standard samples and standard samples
6.1 Standard samples
GB/T4336-2002
Standard products are commonly used for calibration by the calibration line. The quality of the sample is determined by the appropriate concentration of each analytical element in the standard product. The sample is recalibrated at 6.7° due to the change of the instrument state, which leads to the high value of the measured value. In order to ensure the accuracy of the result, the low initial shift curve is used. The sample is recalibrated with a standard sample. This sample is a nuclear sample with a uniform concentration. The net amount of each sample is selected from the standard sample except the upper limit and limit of the standard curve. It can be specially refined. Preparation of the instrument: Only the room temperature should be maintained at 20 °C for the first time and the same standard should be used within the same period of time. The internal change is less than 5 (the design degree is less than 80
7.1 The power supply
is a stable current device. The power supply is less than 10%, and the rate change is less than 2. Ensure that the AC power supply is sinusoidal. According to the secret number, a special ground line is equipped.
72 Excitation light source
To make the light source also work across the main part of the alliance - before starting work, you should use the appropriate medicine to chase the good time: use the power reverse regulator to adjust the power supply voltage to the number required by the device 7.3 The electrodes
need to be replaced and the currency Zong Ni environment certificate is analyzed. The distance between the gap is effective and the depth is maintained at 1. The working state. 7.4 Optical system
The optical mirror must be cleaned and replaced regularly. 5 Photometric system
After shutdown, restart the machine and verify that the sound depth is less than ·°C in order for the photometric system to work properly: The material production must be selected and the appropriate time of the machine must be selected. Experiments must be carried out based on the time pressure to ensure control. 8 Analysis conditions and analysis steps

Calibration line preparation: Under the selected working conditions, the micro-series standard products: Each sample is excited 3 times, and the concentration value of the sample in the standard product is compared with the average value to draw the calibration curve. 8.2.3 The calibration sample is used to calibrate the instrument. The time for calibration depends on the instrument's calibration: 6-2.4 According to the working conditions selected in R.2.2, standard samples and analytical samples are generated. Each sample is recorded in Table 2-3 times. The analysis results are calculated and the content of the analyzed elements is calculated from the calibration curve.
