Abstract(J)ヘリウムは不燃性,無色,無味無臭の不活性希ガスで,多くの科学プロセスや製造プロセスで利用されている.多くの産業がヘリウムに頼っているため,生産,不足,価格などに関する問題が生じており,アプリケーションにヘリウムを使う必要がある場合,様々な影響が生じる可能性がある.ヘリウムの代替ガスとして水素と窒素があるが,水素は大気開放環境下での使用は安全性に問題がある.窒素は平均線速度が小さくなるため分析時間が長くなったり,ピークシグナルが小さくなったりするなどの問題があるため,これらの課題を解決するための検討を行った.

Translation

Abstract(E)Helium is a nonflammable, colorless, tasteless, odorless, inert noble gas that is used in many scientific and manufacturing processes. With so many industries relying on helium, we are experiencing production, scarcity, and price issues, and if your application needs to use helium, it can have a variety of implications. Hydrogen and nitrogen are alternative gases to helium, but hydrogen poses a safety issue when used in an open-air environment, while nitrogen reduces the average linear velocity, resulting in longer analysis times and lower peak values. Since there is a problem, we conducted a study to solve these problems.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
