[Analysis Case] Deodorant Efficacy Test (SIFT-MS)

It is possible to quantify the target compound in the ppt order without creating a calibration curve using the compound library within the device.

In this instance, we will introduce a case where the new efficacy testing method established by the Fragrance Deodorant Association was implemented using SIFT-MS to verify the deodorizing effect of commercially available deodorizing beads. 【Analysis Sample】 Deodorizing beads 【Analysis Device】 SIFT-MS: Voice 200 ultra by Syft Technologies 【Analysis Method】 In this case, deodorizing beads and the specific foul odor substance Trimethylamine (TMA) were added to a 10L Tedlar bag filled with clean air. The TMA concentration in the sampled air was measured using SIFT-MS at regular intervals, and the time required to remove 90% of the foul odor substance (t0.1) was calculated. 【Analysis Results】 The results of measuring the TMA concentration in the Tedlar bag at each time point up to 6 hours after the start of the test are shown. The logarithm of the TMA concentration (C) / initial TMA concentration (C0) was plotted against time, and the time required to remove 90% of TMA (t0.1) was calculated based on the obtained slope (-0.3956). As a result, the time required for the deodorizing beads to remove 90% of TMA (t0.1) was found to be 5.82 hours.
