Isingeniso somkhiqizo

I-CRM isetshenziselwa ukulawula ikhwalithi kanye nokulinganiswa kwamathuluzi okuhlaziya ekuhlaziyeni amalahle.Iphinde isetshenziselwe ukuhlola nokuqinisekisa ukunemba kwezindlela zokuhlaziya.I-CRM ingasetshenziselwa ukudluliswa kwevelu elinganisiwe.

Izindlela Zokuhlaziya

Ithebula 2. Izindlela zokuhlaziya

Ukwakheka	Indlela
P	Indlela ye-photometric ye-molybdophosphate eyehlisiwe I-ICP-AES
As	HG-ICP-AES HG-AFS
F	Ukuhlaziywa kwe-electrode ye-fluorine ion-selective I-chromatography ye-ion
Cl	Indlela ye-potentiometric titrimetric I-chromatography ye-ion
Hg	Indlela ye-spectrometric yokumuncwa kwe-athomu ebandayo ye-AFS Isampula eqinile kanye nendlela yokuhlaziya i-mercury eqondile

Ukuhlolwa Kwe-Homogeneity Nokuhlola Ukuzinza

Ukuphelelwa yisikhathi kwesitifiketi: Isitifiketi sale CRM sisebenza kuze kube umhlaka-1 Juni 2024.

Ithebula 3. Izindlela zokuhlola i-homogeneity

Ukwakheka	Izindlela zokuhlaziya	Isampula elincane (g)
P	I-ICP-AES	1
As	HG-ICP-AES	1
F	Ukuhlaziywa kwe-electrode ye-fluorine ion-selective	0.5
Cl	Indlela ye-potentiometric titrimetric	0.5

Ukupakisha Nokugcina

Izinto eziyisethenjwa eziqinisekisiwe zipakishwe emabhodleleni engilazi ansundu anamakhava epulasitiki.Isisindo senetha singama-50 g lilinye.Kuphakanyiswa ukugcina ukoma lapho ugcinwe.
