Kuyambitsa mankhwala

CRM imagwiritsidwa ntchito poyang'anira khalidwe ndi kuwongolera zida zowunikira powunika malasha.Amagwiritsidwanso ntchito poyesa ndi kutsimikizira kulondola kwa njira zowunikira.CRM ingagwiritsidwe ntchito kusamutsa mtengo woyezedwa.

Njira Zowunika

Gulu 2. Njira zowunikira

Kupanga	Njira
P	Njira yochepetsera molybdophosphate photometric ICP-AES
As	HG-ICP-AES HG-AFS
F	Fluorine ion-selective electrode kusanthula Ion chromatography
Cl	Njira ya potentiometric titrimetric Ion chromatography
Hg	Cold atomic mayamwidwe spectrometric njira AFS Sampling yolimba komanso njira yowunikira molunjika mercury

Kuyesa kwa Homogeneity ndi Kuwunika Kukhazikika

Kutha kwa certification: Chitsimikizo cha CRM iyi ndichovomerezeka mpaka June 1, 2024.

Table 3. Njira zoyezetsa homogeneity

Kupanga	Njira zowunika	Zitsanzo zochepa (g)
P	ICP-AES	1
As	HG-ICP-AES	1
F	Fluorine ion-selective electrode kusanthula	0.5
Cl	Njira ya potentiometric titrimetric	0.5

Packing Ndi Kusunga

Chidziwitso chotsimikizika chimayikidwa m'mabotolo agalasi ofiirira okhala ndi zovundikira zapulasitiki.Kulemera kwake konse ndi 50 g iliyonse.Zimalangizidwa kuti zisunge zowuma zikasungidwa.
