Abstract
Vacuum gauges are arranged in intermediate vacuum chamber and analytical chamberin which collision cell is installed, and gas pressure determination unit determines whether or not the gas pressures detected by vacuum gauges are at or below a threshold value prior to analysis, and issues an alert if they are at or below the threshold value. If the supply of CID gas into collision cell stagnates, the quantity of CID gas flowing out into the analytical chamber will decrease, and the degree of vacuum in the analytical chamber will thus become too high. Furthermore, if the heated capillary becomes clogged, the quantity of gas flow into the intermediate vacuum chamber from the ionization chamber, which has an ambient pressure atmosphere, will decrease, and thus the degree of vacuum inside the intermediate vacuum chamber will become too high.
