直读光谱仪对氩气的要求
<p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%; font-family: Calibri; font-size: 11pt; mso-spacerun: &quot;yes&quot;; mso-fareast-font-family: 宋体; mso-bidi-font-family: &quot;Times New Roman&quot;; mso-font-kerning: 1.0000pt;">高纯度的氩气对直读光谱仪来说是不可或缺的,不少厂家为了节省成本会采用自己灌装或者采购的低纯度氩气,虽然也能够使用但对于光谱仪的检测结果还是会有影响的。</span></p><p style="margin: 0pt; line-height: 1.75em;"><span style="color: rgb(0, 0, 0); line-height: 150%;
