When the hand-held spectrometer is used, it has certain requirements for the environment. Don't work in a humid environment. The humidity of the environment is 0-95%, so it is best not to operate at too high a temperature. The reason is to avoid the interference of various magnetic fields and make the instrument detect more accurate accuracy in analysis. Therefore, everyone should pay attention to the suitability of the environment when working. In many cases, the detection of non-standard instruments still has a great relationship with the environment.
First of all, hand-held spectrometer also has certain requirements for operators. Before testing the sample, the technicians of the instrument manufacturer must be invited to give a live demonstration and trained before operating. Because this instrument is a testing element, it needs lofting testing, and it is still in use for human body, so technicians need to do radiation protection.
Second, when using the instrument to detect samples, the technicians operating the instrument should first aim the round hole in front of the instrument at the point where the sample needs to be detected and stick the instrument on it. When pulling the trigger to start testing, the technician's hand must not shake or deviate, otherwise it will affect the test data results.
Third, there are also some small requirements for the samples to be tested. The surface of the measured object must be smooth and tidy to avoid interference from other elements. The surface of the detected object is polluted by oil or heavy metals, so the accuracy of the detection results is not so high, and no instrument can cover everything.
In fact, the operation of hand-held spectrometer looks complicated, but if you follow the instructions of technicians step by step, it is not as complicated as you think.
