In the field of cultural relics detection, samples are often required to be sealed before detection after collection. For example, when silk is traced by using an isotope technology, after a fresh mulberry leaf and mulberry twig sample is collected in the field, it is considered that various microorganisms (aerobic bacteria, anaerobic bacteria and the like) in the nature can use the mulberry leaf and mulberry twig containing carbon and nitrogen elements as a carbon source and nitrogen source required by growth and propagation of the mulberry leaf and mulberry twig. Therefore, after the samples are collected, the samples need to be treated promptly to prevent microorganisms (aerobic bacteria, anaerobic bacteria and the like) from corroding the samples, influence the values of carbon and nitrogen isotopes of the samples to cause errors of isotope source tracing data, reduce natural fractionation of the carbon and nitrogen isotopes, and keep production place information as much as possible. Therefore, prior to detection of carbon and nitrogen stable isotopes, it is necessary to address the problem of sample storage prior to processing.
