Cleaning Spark Stand of Optical Emission Spectrometer

Description: Clean the spark stand where the samples are placed with professional tools.

Purpose: To keep the spark stand clean and avoid residue (sediment) interference.

Methods: Open the spark stand cover, with a soft brush, the spark stand in the residue (sediment) cleaning, and then cover the spark stand cover, and with a high flow of argon gas blowing for more than 2 minutes.

Spark stand is the position of the spectrometer's emission spectrum, some performance indicators here determine the spectral line is good or bad. If not cleaned in time may cause the following situations: short circuit between the electrode and the spark stand.

For safety, make sure the light source switch is off before proceeding with cleaning. Loosen the four screws on the spark stand plate, remove the plate and gasket or ring, and carefully remove the quartz sleeve and quartz gasket. This will allow you to clean the inside of the spark stand with a hoover. After cleaning, install the table plate and fix the electrode in the middle with the centre gauge. After the four screws are tightened, adjust the distance between the electrode and the spark stand by turning the gauge upside down. Turn the light switch on, click the flushing button in the menu, so that the entire circuit of argon gas flushing 2-3 minutes to flush out the incoming air.

To clean the spark stand, first clean the upper part as described above while making sure the power is off. Then, disconnect the lower part of the high-voltage cable, with the instrument with the inner hexagonal plate hand to remove the lower part of the pin, remove the lower part of the four thumbscrews, gently remove the insulating material for the bottom bracket. Use the inner hexagonal hand to turn the pin from the hole where the electrode is fixed to a suitable position, and then turn it upwards or downwards to remove the copper rod that holds the electrode. Remove the white nylon sleeve in the centre of the spark stand by gently vibrating it downwards, you will notice that it is dirty.
