Sampling manner and picking body null for infrared ray gas analysis by absorption method

摘要

PROBLEM TO BE SOLVED: To provide a method and sampler by which such a very small amount of sample that is bled from an object can be collected efficiently and immediately. ;SOLUTION: In a sampler for infrared-absorbing analysis provided with a sampling sheet 1, composed of a polytetrafluoroethylene sheet or polyethylene sheet at the through hole section of a supporting substrate 3 having a through hole 2 formed in a prescribed size, one surface of the sampling sheet 1 is covered with a contact preventing sheet 4 which does not substantially absorb intermediate-infrared rays, and the other surface of the sampling sheet 1 is exposed.;COPYRIGHT: (C)1999,JPO
