Method for preparing standard sample for gas flow type analysis system
An object of the invention is to improve uniformity of a standard sample used for evaluating a gas flow type analysis system. The invention includes weighing a background into a container; adding a sample solution to the background; drying the sample solution; adding a solvent that can dissolve the sample into the container; and drying the solvent added to the container. The invention is also characterized in that the solvent is an organic solvent, in particular, acetone.
1. A method for preparing a standard sample for a gas flow type analysis system, comprising:
weighing into a container a background, which is particulates, that is possibly attached to a test subject at the time of performing a test by the analysis system for analyzing an attached substance attached to the test subject;
adding a solution of a sample to the background;
drying the solution of the sample;
adding acetone into the container to a level that is higher than a level of the sample deposited on a wall surface of the container; and
drying the acetone added into the container.
2. A method for preparing a standard sample for a gas flow type analysis system for analyzing an attached substance attached to a test subject, comprising:
generating a suspension containing a background at a desired concentration;
adding dropwise the suspension onto a sheet-like substance;
drying the suspension on the sheet-like substance;
adding dropwise a solution of a sample to the dried suspension; and
drying a solution of the suspension and the solution of the sample.
