Basic Requirements for Spectrometer Installation
A photoelectric direct-emission spectrometer is a precision instrument that combines photoelectricity and light. To produce accurate data, it must operate under certain operating conditions. Proper use, maintenance, and installation are prerequisites for proper operation, extended service life, and accurate data reporting. Therefore, when installing the instrument, it is crucial to thoroughly understand its principles and practical operation, and to prepare installation conditions in accordance with the instrument's manual. Like other precision instruments, even slight changes in the external environment can affect the stability of measured data. Therefore, laboratory design and site selection primarily consider environmental and supporting requirements. Environmental requirements are paramount, primarily encompassing room size, vibration and electromagnetic sources, noise, dust content, doors, flooring, humidity, and temperature.
When selecting a laboratory site, consider factors such as room size, vibration, and electromagnetic sources. The room should be of moderate size. If it is too small, the room becomes crowded and difficult to operate. If it is too large, the room temperature becomes difficult to control, wasting energy. The room should be located away from vibration sources, such as in stamping shops, railways, and tensile laboratories. This is because the spectroscopic (dispersion) system is a critical component of a photoelectric direct-reading spectrometer, and the positions of its optical components are calibrated before shipment. The grating, a crucial component of the dispersion system, must be fixed and cannot shift. During the measurement process, if the instrument vibrates, the grating's position may shift, increasing stray light and affecting the accuracy of the results. In severe cases, the signal cannot be detected or is very weak, directly impacting the measurement. Furthermore, small full-spectrum benchtop spectrometers (CCDs) should be installed on a fixed concrete workbench with an anti-vibration foundation. The workbench's vibration and impact resistance must be at least 10 g's, and the laboratory floor must be free of noticeable vibration. Furthermore, proximity to electromagnetic sources can affect the performance of the instrument's electrical components. Therefore, the room should be located away from high-frequency generators such as intermediate-frequency furnaces and transformers. The laboratory should have minimal electromagnetic interference, be immune to electromagnetic interference, and have an RF signal attenuation greater than 10³.
