Abstract

The chemical amplification (PERCA) method has been widely used for measuring peroxy radicals concentrations in the troposphere. The accuracy and sensitivity of the method is critically dependent on the chain length (CL) - that is, the number of radical amplification cycles. However, CL decreases strongly with higher relative humidity (RH). So far, there does not appear to be a method to overcome this impact. Here we report the development of a Nafion® dryer based dual-channel PERCA instrument. The large diameter Nafion® dryer efficiently removes water vapor in milliseconds and minimally affects the sample. The low losses of peroxy radicals on the NafionTM membrane make it an attractive tool for raising the CL, and thereby the measurement accuracy and sensitivity of PERCA systems. The reported instrument demonstrates this promising and simple method to minimize water vapor interference.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 March 2018.
All research outputs
#3,156,780
of 23,023,224 outputs
Outputs from Analytical Chemistry
#1,830
of 26,624 outputs
Outputs of similar age
#76,949
of 446,267 outputs
Outputs of similar age from Analytical Chemistry
#52
of 545 outputs
Altmetric has tracked 23,023,224 research outputs across all sources so far. Compared to these this one has done well and is in the 86th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 26,624 research outputs from this source. They receive a mean Attention Score of 4.7. This one has done particularly well, scoring higher than 92% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 446,267 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 82% of its contemporaries.
We're also able to compare this research output to 545 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 90% of its contemporaries.
