AB: If you are doing fundamental sample prep, you may about hope a life span of 200 to 500 injections based on your matrix complexity. Should you have matrix parts that are likely to clog the inlet frit or an important sample precipitation you might see a reduced life span. In general, the purpose should be to raise the life time of one's analytica

Given that some electrolyte will usually leak to the sample in the course of measurement, It is usually vital the electrolyte not react Using the measurement Answer.pH Meter Theory: It steps the voltage among the two electrodes, just one is actually a glass electrode, and the opposite is actually a reference electrode. In some cases, if the two ele
