About Sample Handling	・As a general rule, samples will be returned after analysis is complete. ・Since Thermal Desorption Spectroscopy (TDS) is a destructive analysis involving heating, samples may undergo changes during measurement. ・Depending on the type of sample and measurement conditions, sample recovery may be difficult due to volatilization or other factors.
