“PPM”是體積比濃度。“PPM”是溶液濃度的一種表示方法， PPM 表示百萬(wàn)分之一。對(duì)于溶液：即1升水溶液中有1/1000毫升的溶質(zhì)，則其濃度為1 PPM 。對(duì)于氣體：對(duì)環(huán)境大氣中污染物濃度的表示方法之一。體積濃度表示法：一百萬(wàn)體積的空氣中所含污染物的體積數(shù)，即PPM ，大部分氣體檢測(cè)儀器測(cè)得的氣體濃度都是體積濃度（ PPM ），而按我國(guó)規(guī)定，特別是環(huán)保部門(mén)，則要求氣體濃度以質(zhì)量濃度的單位表示，我們國(guó)家的標(biāo)準(zhǔn)規(guī)范也都是采用質(zhì)量濃度單位表示。它是利用一些金屬氧化物半導(dǎo)體材料，在一定溫度下，電導(dǎo)率隨著環(huán)境氣體成份的變化而變化的原理制造的。四川氣體檢測(cè)儀器推薦</p><p
