Lub tshuab tua hluav taws yog qhwv los ntawm cov plua plav npog thiab tsis tuaj yeem ceeb toom ib txwm. Vim tias cov khoom siv hluav taws xob feem ntau yog cov khoom siv hluav taws xob. Qhov ntawd yog, yuav tsis muaj lub tswb ceeb toom kom txog thaum kuaj pom cov pa luam yeeb. Thaum cov pa luam yeeb tau ntim rau hauv lub npog plua plav, nws tsis tuaj yeem nkag mus rau qhov ntsuas hluav taws, yog li cov pa luam yeeb tsis tuaj yeem ntes tau thiab lub tswb yuav tsis qhib.
Nyob rau hauv ib txwm muaj xwm txheej, cov cuab yeej hluav taws xob raug txwv nruj kom tsis txhob npog nrog cov tshuaj ntsiav kom tsis txhob txo qhov rhiab heev lossis ua rau tsis ua haujlwm. Yog hais tias qhov kev ua hauj lwm ntawm lub detector yog heev thiab cov pa luam yeeb concentration nyob rau hauv tej yam ntuj tso ib puag ncig yog siab, nws raug nquahu kom yuav thiab siv lub tswb ntsuas hluav taws xob thiab lub tswb ceeb toom kev nyab xeeb rau kev ua haujlwm tshwj xeeb.
Cov pa luam yeeb yuav tsis suab lub tswb kom txog thaum lub npog plua plav tawm ntawm lub hoobkas. Cov pa luam yeeb tsuas ua rau lub tswb nrov thaum cov pa luam yeeb nkag mus rau hauv lub tshuab kuaj kab mob. Ntau tus neeg siv tsis paub tshem cov plua plav npog tom qab siv lub tshuab nqus pa, uas yog qhov txaus ntshai heev.
