Effect of temperature on Optical Emission Spectrometer

Here the influence of temperature on the Optical Emission Spectrometer refers to the indoor temperature. Don't get it wrong!  In fact, different types of laboratories have different requirements for room temperature.  It can be seen from the Optical Emission Spectrometer instructions that most of the ambient temperature is set between (20-26) ° C, and the temperature change per hour should be less than 1 ° C.

Generally speaking, precision optical instruments have certain requirements for the ambient temperature. Parts made of different materials will also distort and deform due to different expansion coefficients, which will deviate from the basic reference. The heat dissipation efficiency of its optical components and instruments will reduce changes.  This small change will cause the performance of the optical system to change; a higher room temperature will reduce the heat dissipation efficiency of the instrument, which will lead to a decrease in the performance of the electronic components of the instrument due to the increase in temperature inside the instrument, a shorter service life, and a lower insulation performance.  For example, in the ICP Optical Emission Spectrometer, the optical element is subject to changes in the ambient temperature, which will cause spectral line drift, which will result in too high precision of the measurement data and it will be difficult for the operator to accurately measure the data. Low temperature will change the parameters of the capacitive inductor resistor and cause performance Changed.  Since electronic components, especially integrated circuits, are required to work within a suitable temperature range, in order to ensure the accuracy of the instrument and extend its service life, the instrument should always be at the required ambient temperature.  If the ICP Optical Emission Spectrometer exceeds the setting range of the ambient temperature during the working process, there will be failures such as inaccurate peak detection, inability to analyze, and measurement of standard sample data.  Time has shown that temperature instability and large changes can cause the data detected by the sample to exceed 10% of the specimen.  Therefore, in order to ensure the normal operation of the spectrometer and human physiological characteristics, it is recommended to set the optimal range of the ambient temperature at (21 ~ 26) ° C, and the change of the ambient temperature within 2h should be less than ± 1 ° C.
