PROBLEM TO BE SOLVED: To solve the point at issue such that a conventional instrument used in the chemical analysis of environment has a system for cutting off the open air by loading a disposable type aluminum cap requiring a special tool with a thin film-like packing or a screw cap system exclusive to a small volume sample bottle and using the thin film-like packing and, therefore, resources are wastefully used and the thin film-like packing incapable of withstanding repeated use must be employed. SOLUTION: The sample or generated gas in a sample bottle can be sampled and analyzed by loading the upper opening part of a screw cap with a thick elastomer septum type adaptor or a cylindrical adaptor. This instrument has an inexpensive structure usable in combination with a recycled sample bottle and is useful in a chemical analysis field. |
