Amashubhu wokuhlola amaCod: Imiyalo Nezindlela Zokuqapha

Ukuthambekela kokugaya izinto zombala wokugayeka emakethe kwenziwa kube ngu-16mm, futhi ukubekezelela ibhodlela le-tube yengilazi kukhulu kakhulu ± 0.2mm, ngakho ububanzi beshubhu lokuhlola bukhulu kakhulu 15.75 ± 0.2mm.

Ukuphakama kweIshubhu lokuhlolauvame 90, 100, 110, 125, 130, 150mm. Ngokusho kwezilinganiso ezihlukile ze-realent zomenzi ngamunye, ukuphakama kuhlukile futhi. Phakathi kwazo, okusetshenziswa kakhulu yi-100mm test tube.

Izinto ze-COD zokuhlola amashubhu

Izinto ze-I-COD test tubengokuvamile ziphansi kakhulu, ezingathathi hlangothi ze-borosiliLate, kanye ne-borosilivate ephezulu. Zingasetshenziswa uma kungekho umbala we-colorimetry uyadingeka. Lapho ukugaya ikhono lokugaya kwamanzi kanye ne-colorimetry kuyadingeka, izinto ezikhethiwe azithathi hlangothi i-borosiliLile.

Kunezinhlobo ezintathu zezinto zokwenziwa kwesembozo: i-polypropylene emhlophe yokusetshenziswa kwesikhathi esisodwa; esobala polycarbonate yokusetshenziswa okuphindaphindiwe; I-Black Phenolic Resin yokusetshenziswa okuphindaphindwayo kwamashubhu wokuhlola ngaphezulu kwe-110mm.

Ngeminye imininingwane ngamashubhu wokuhlola ama-COD kanye nezicelo zawo ekuhlaziyweni kwamanzi, bhekani kulesi sihloko:"I-COD Test Tube isetshenziswa kanjani ekuhlaziyweni kwamanzi."

Ukugaya ukugaya izinyathelo zokuphepha

1. Sebenzisa ithuluzi lokugaya elifanelana phansi kweshubhu. Amabhodlela ayindilinga ahambisana namathuluzi wokugaya aphansi aphansi, futhi ama-bottops aphansi ahambisana namathuluzi okugaya aphansi aphansi. Ngaphandle kwalokho, ukufudumala okungalingani kuzodala i-tube ikhuphuke. Lapho ubeka ishubhu lokuhlola, kufanele ibekwe kancane ukugwema ukuqhuma okubangelwa ukushayisana okunobudlova kwe-boobe yokugaya okunomgodi wokugaya. Ngokwesipiliyoni esedlule, amanye amashubhu okugaya aqhuma ngenxa yokusebenza okungafanele.

2. Gwema ukusebenzisa ukugaya amashubhu namabhobhuka ngemicu ebekiwe. Ama-Mismaches ngeke anciphise futhi avuza. Kuncike ikakhulukazi ekutheni kubushelelezi lapho kusonteka. I-Smooth futhi ibushelelezi futhi isembozo ayisigwegwe kakhulu ukuba sihlangabezane nezidingo.

3. Gwema ukuklwebheka okuningi. Amashubhu namashubhu azoba nemihuzuko lapho ehlikihla. Ukuhlanza ibhodlela nakho kulula ukudala ukuklwebheka. Amaphuzu angamaphoyinti abuthakathaka wamandla weshubhu.

4. Gwema ukusebenzisa amabhodlela alimele namabhodlela. Ngenxa yokungenelela okwenziwa ngesandla ngesikhathi sokuhamba nokukhiqizwa, imikhiqizo enjalo ayinakugwenywa. Musa ukusebenzisa amabhodlela namabhodlela anephutha.

5. Ungagadi amasampula wamanzi ngqo. Kufanele ube nama-reagents ahambisanayo. Iphuzu lamanzi elibilayo liphansi kakhulu. Amanzi amaningi akhona, okuphezulu kakhulu kwengcindezi ebhodleleni kuzoba, futhi isivalo ngeke sikwazi ukubamba. Uma udinga ukugaya amasampula amaningi wamanzi, sicela usebenzise isivalo esinamandla futhi esishisa ngokushisa.

6. Ukuthatha isinqumo se-Cod Index ngamasampula wamanzi njengesibonelo, ngoba amanye amakhemikhali amakhemikhali adinga ukungezwa kwisampula yamanzi ngaphambi kokugaya, uma kungahlanganisi ngokulinganayo, kungadala ukuthi isampula lokugaya libilise ngesikhathi sokugaya futhi libangele ukuba ligaye ishubhu. Ngakho-ke, isampula yamanzi kufanele ixutshwe ngokulinganayo ngaphambi kokugaya ukuvikela ishubhu lokugaya kusuka ekuqhuti.

Ukuqhathanisa Ukuqapha

1. Shake kahle ngaphambi kokuqhathanisa. Ngaphambi kokubeka ishubhu lokuhlola ku-photometer, sula ishubhu lokuhlola lihlanzekile ngendwangu yeshubhu lokuhlola.

2. Khetha ithuluzi elilinganiselwe kanye nedivayisi yokuphamba ngephutha elincane lokugwema amaphutha amaningi adalwa abasebenzi kanye nemishini.

3. Uma kukhona ukubhala, musa ukuvumelanisa indawo yokubhala ngesikhundla sokuqhathanisa.

I-4. Ekugayweni okusheshayo okuvela i-spectrophotometry, imfuneko ye-colorimetric tube ukuthi iphutha lokumunca elingaphakathi ± 0,005, okungukuthi, ngaphakathi kwamayunithi ayi-10, ngakho-ke amashubhu we-colorimetric afanayo kufanele abe ngaphakathi kwephutha ngangokunokwenzeka. Uma ama-20% amashubhu ku-batch adlula ibanga lephutha, amashubhu we-colorimetric aleli batch awafaneleki.

5. Sicela usebenzise amanzi ahlanzekile ukuvivinya iphutha le-tube.

[Amathiphu wokuqhathanisa we-colorimetric]

Lapho ukuqhathanisa kombala we-colorimetric, ungavivinyi kuphela i-angle eyodwa kuphela, ngoba kulula ukuba namaphutha kumanani aphezulu nawaphansi, noma kungenzeke nje ukuthi ingaphezulu kwakho lihlola linamabala noma uthuli. Kungcono ukuhlola izindawo ezintathu ngeshubhu elifanayo. Uma amanani ama-surface amathathu angaphakathi kwe- ± 0.005, sebenzisa la manani amathathu ukuthatha isilinganiso njengomphumela wokuhlolwa. Lokhu kugwema amaphutha abangelwa ukuklwebheka futhi uvikele ukuthatha inani eliphakeme lephutha le-tube. Uma ishubhu elifanayo lithathwa izikhathi ezingaphezu kwezingu-6 futhi namanje alikwazi ukuthola amanani amathathu ngaphakathi ku- ± 0.005, khona-ke kunenkinga naleli tube (ukufana akukuhle).

Ukuqonda okujulile kokuthi ama-cod vials asebenza kanjani ekuhlolweni kwamanzi, sicela ubheke kule ndatshana:"Umgomo osebenzayo we-COD Vial. "
