Benefits of technology

This innovation improves upon existing sensors for detecting alkaline gases such as formaldehydins (a type of chemical compound used widely throughout industry). Unlike previous methods where there was no ion selective filter or other means involved, these novel sensors use a special material called PF-5 instead of pure hydrogen fluorescein labeled at room temperatures. By replacing certain acids like sulfur hexadecyltrisilicate with another substance called pfluroroacetic acid, they are able to improve their performance over time without losing any ability to absorb light signals from specific molecules being analyzed. Additionally, the inventions have improved durability against environmental factors including heat and cold while also reducing its size compared to older designs. Overall, these improvements make them more efficient than current technologies but still work well even under harsh conditions.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of an electric chemical vapor detector (EVC) that uses formaldehydic substances like methanol or urea instead of harmful gases such as carbon monoxide. However, current methods have limitations with regard to storing strongly alkaline liquids within the ECV's sensing area without causing damage from moisture.

Abstract

The invention discloses a novel formaldehyde sensor comprising a casing. An electrode carrier, a working electrode and a counter electrode are fixedly connected to the inner side wall of the casing. Aworking electrode lead and a counter electrode lead are connected to the working electrode and the counter electrode respectively; and one end of each of the working electrode lead and the counter electrode lead passes through the casing and extends to the outside. Therefore, the outer dimension of the casing is reduced; and a phenomenon of the sensor abnormity caused by the internal resistance increasing due to dehydration of the perfluorinated proton exchange membrane is avoided.
