Abstract:
In-plane distribution of a target objectcontained in a sample is measured. The sample dispersedly placed on a substrate is treated to promote ionization of the target object, then the mass and flying amount of an ion containing the target object or a component of the target object is determined by irradiating an ion beam to the sample and performing time-of-flight secondary ion mass spectrometry of the ion that flies from a portion in the sample where the ion beam is irradiated, and the in-plane distribution of the target object is determined from the mass and flying amount data obtained at plural portions by scanning the beam on the sample plane. The step of treating the sample to promote ionization of the target object includes contacting an aqueous solution of an acid that does not crystallize at ordinary temperature with the sample. A high spatial resolution two-dimensional image can be obtained.

Abstract:
The reading timing determination unit determines a timing at which identification marks such as print bar codes should be read. The reading unit reads identification marks in accordance with the timing to provide identification mark data in a numerical form. The discrimination unit compares identification mark data with data value of an identification mark to be primarily printed to judge whether or not the identification mark is correctly printed. The signal generation unit produces a notifying signal when it is judged that the identification mark is not correctly printed. In this way, this apparatus tests whether or not identification marks successively printed on a moving body in the form of sheet by the printing machine are correctly printed.
