Is it Better to Choose a Single-element Lamp or a Multi-element Lamp for Atomic Absorption?

Each element lamp needs to be preheated after it is replaced. Normally, it should be within 30 minutes. The sample test can be performed after the preheating. In this way, if the multi-element lamp can be preheated at the same time, it can save the time and time of lamp replacement. Warm-up time, improved efficiency, and reduced replacement frequency will also reduce the loss of the instrument. On the other hand, multi-element lamps may interfere with multiple elements, causing instability in the absorption of different wavelengths. At the same time, the repair and replacement price of multi-element lamps is higher than that of single-element lamps. Therefore, the two types of lamps have their own advantages and disadvantages.
