Packed column for analysis and determination of formaldehyde and acetaldehyde
Packed column for analysis and determination of formaldehyde and acetaldehyde Details:

Name: Packed column
Stationary phase: dedicated
Specification: 2m*3mm
Material: PTFE tube
Model: HH-Modified polymer

The derivatization conditions of the amount of formaldehyde and acetaldehyde, the derivatization reaction of formaldehyde, acetaldehyde and 2,4-dinitrophenylhydrazine solution heated in a 60℃ water bath for 60 min, this method is complicated to operate, time-consuming, laborious, and not environmentally friendly.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a special packed column HH-Modified polymer to directly determine formaldehyde and acetaldehyde. The result is that the resolution of formaldehyde and acetaldehyde is 3.6, and the linear range of formaldehyde is 0.028~9.23μg.mL 1(r =0.999 4), the average recovery rate (n=9) was 102.6% (RSD=0.9%), the limit of quantification was 3.7×10 6 μg, and the limit of detection was 1.8×10 6 μg; the linear range of acetaldehyde was 0.063-20.90 μg. mL 1 (r=0.999 5), the average recovery rate (n=9) was 102.0% (RSD=1.2%), the limit of quantification was 1.1×10 4 μg, and the limit of detection was 5.5×10 5 μg. Conclusion This method is accurate and sensitive, and provides a basis for the safety monitoring of formaldehyde and acetaldehyde.
