Phosphate analyzers siv lub microcomputer -tswj photoelectronic colorimetric nrhiav kom tau txoj hauv kev, hloov cov qauv kev pom xim xim. Qhov no tshem tawm tib neeg kev ua yuam kev, yog li txhim kho kev ntsuas kev daws teeb meem.
Tam sim no, cov dej phosphate analyzers feem ntau siv cov qauv kev tshawb nrhiav xws li tshuaj lom neeg xim (spectrophotometry), ion chromatography, thiab electrode txoj kev. Lub hauv paus ntsiab lus tseem ceeb ntawm chemical colorimetry (spectrophotometry) yog siv tshuaj lom neeg los hloov phosphates hauv dej rau hauv cov xim sib xyaw. Tom qab ntawd lub absorbance ntawm cov xim sib xyaw yog ntsuas los ntawm kev siv lub spectrophotometric module. Raws li kev sib raug zoo ntawm kev nqus thiab phosphate concentration, phosphate cov ntsiab lus hauv cov qauv yog xam.
Lub hauv paus ntsiab lus ntawm ion chromatography zoo ib yam li cov ion chromatography analyzers. Phosphate ions hauv cov qauv dej yog sib cais siv ib qho ion- pauv chromatographic kem. Cov teeb liab phosphate sib cais yog tom qab ntawd kuaj pom siv lub ntsuas hluav taws xob rau kev ntsuas ntau. Cov txheej txheem electrode siv cov phosphate tshwj xeeb- cov electrode xaiv, tsim cov galvanic cell nrog cov khoom siv electrode. Thaum cov electrode tso rau hauv cov qauv dej, phosphate ions cuam tshuam nrog cov rhiab membrane ntawm electrode nto, ua kom muaj qhov sib txawv ntawm cov phosphate concentration. Kev ntsuas qhov sib txawv no tso cai rau kev suav cov phosphate concentration. Ntawm lawv, cov txheej txheem tshuaj colorimetric tau dhau los ua cov thev naus laus zis siv dav tshaj plaws vim lawv txoj haujlwm yooj yim, tus nqi nruab nrab, thiab rhiab heev uas ua tau raws li qhov xav tau ntawm kev tshawb nrhiav niaj hnub.
