Title:
STANDARD SAMPLE FILM, METHOD FOR PRODUCING STANDARD SAMPLE FILM, STANDARD SAMPLE, SAMPLE SET, QUANTITATIVE ANALYSIS METHOD, AND TRANSFER FILM
Document Type and Number:
WIPO Patent Application WO/2023/013417
Kind Code:
A1
Abstract:
The present invention provides: a standard sample film or a standard sample, which is used for laser ablation inductively coupled plasma mass spectrometry, the standard sample film or the standard sample containing an organic material and having a small variation in the signal intensity of ions of a metal element according to the measurement positions; a method for producing a standard sample film; a sample set; a quantitative analysis method; and a transfer film. A standard sample film according to the present invention is used for laser ablation inductively coupled plasma mass spectrometry; and this standard sample film contains a polymer, a metal element and an internal standard, while having a maximum height difference in the film thickness of the standard sample film of 0.50 μm or less.
