**應(yīng)用參考 · INSTRUCTION**
為鑒定或確認(rèn)分析物******濃度不致于引起超過合約檢出限CRDL的記憶效應(yīng),不直接測試此標(biāo)液,而是等份兩溶液CL-MEM-1和CL-MEM-2混合并引入儀器,停留與樣品測試同樣的時間,然后引入空白,以確認(rèn)所有分析物記憶效應(yīng)都低于合約檢測限CRDL。
To identify or confirm the maximum concentration of an analyte that does not cause a memory effect greater than the contract required detection limit (CRDL). The test solutions are not analyzed directly; equal volumes of the two are mixed and then introduced into the instrument for a normal sample exposure time. A blank is then run to confirm that all analyte memory effects are below the CRDL.
