**應(yīng)用參考 · INSTRUCTION**
合約檢出限和儀器檢出限高者,需運(yùn)行標(biāo)液于2倍檢出限值進(jìn)行檢測(cè)。樣品測(cè)試開始和結(jié)束前檢測(cè)檢出限,或者8小時(shí)班至少2次檢測(cè)檢出限。所有測(cè)試到的元素都需檢測(cè)檢出限,除了Al, Ba, Ca, Fe, Mg, Na, K元素。標(biāo)液CRDL-1,對(duì)于ICP,在運(yùn)行2倍檢出限值檢測(cè)前,應(yīng)稀釋1000倍使用;對(duì)于AA,在1倍值檢測(cè)前,應(yīng)稀釋2000倍使用。
A standard must be run at two times the Contract Required Detection Limits (CRDL), or at two times the Instrument Detection Limits (IDL), whichever is greater. This standardization is performed at the start and the end of each sample analysis or at least twice in each eight hour shift. All elements to be analyzed must be run except Al, Ba, Ca, Fe, K, and Na.
Our CRDL-1 standard contains all of the required elements on the TAL, in their appropriate concentration ratios. CRDL-1 should be diluted by a factor of 1,000 prior to use in the “two times CRDL” run for ICP-AES analysis. For analysis by atomic absorption, CRDL-1 should be diluted by a factor of 2,000 prior to use in the “one time CRDL” run.
