Í fyrsta lagi, frá sjónarhóli kostnaðar, getur fjölbreytugreiningarbúnaður greint mörg gögn í einu, en búnaður með einum breytu getur aðeins greint eina breytu fyrir vatnsgæði í einu. Ef þú þarft að greina margar breytur þarftu að breyta búnaðinum fram og til baka og bæta samsvarandi greiningarefnum við sýnið hverju sinni. Þess vegna er tilraunakostnaðurinn oft mun hærri en fjölþátta tækið.

Í öðru lagi, hvað varðar nákvæmni greiningargagnanna, skynjar vatnsgæðagreiningarinn með mörgum breytum mörg gögn lausnarinnar á sama tíma. Þess vegna geta nokkrar villur komið fram við greininguna, sérstaklega þegar greiningartíðnin er mikil. Stakgreiningartækið greinir stök gögn lausnarinnar og þátturinn sem truflar niðurstöðu greiningarinnar er mjög lítill svo gögnin eru í grundvallaratriðum ekki röng. Hins vegar eru flestir margbreytu vatnsgæðagreiningar mældir í lotum og truflunin milli breytanna er lítil. Þó að aðgerðin sé þægileg minnkar gagnavilla greiningarniðurstaðna verulega.

First, from a cost perspective, multi-parameter analysis equipment can analyze multiple data at a time, while single-parameter equipment can only analyze one water quality parameter at a time. If you need to analyze multiple parameters, you need to change the equipment back and forth, and add corresponding analysis reagents to the sample each time. Therefore, the experimental cost is often much higher than the multi-parameter instrument.  Secondly, in terms of the accuracy of the analysis data, the multi-parameter water quality analyzer detects multiple data of the solution at the same time. Therefore, some errors may occur in the analysis, especially when the analysis frequency is high. The single parameter analyzer detects the single data of the solution, and the factor that interferes with the analysis result is very small, so the data is basically not wrong. However, most of the multi-parameter water quality analyzers are measured in batches, and the interference between the parameters is small. While the operation is convenient, the data error of the analysis results is greatly reduced.  Therefore, these two water quality analyzers have their own characteristics. If you want to save costs or just preliminarily test multiple water quality data, you can choose multi-parameter testing equipment. If the requirements for water quality analysis results are relatively high, you can consider using a single analytical instrument

Þess vegna hafa þessir tveir vatnsgæðagreiningar sín sérkenni. Ef þú vilt spara kostnað eða bara prófa mörg gæðagögn vatnsgæða geturðu valið prófunarbúnað fyrir fjölbreytur. Ef kröfur um niðurstöður vatnsgæðagreiningar eru tiltölulega háar geturðu íhugað að nota eitt greiningartæki
