Instead of using subjective visual comparisons of gross vehicle weight (GVW) distributions, this research implements a peak-range check, peak-shift check, and correlation analysis to quantify the ALS comparison process of rational checks.
As a consistency check, peaks from both azimuths on each sample were used.

This technique is used as one of the methods of double checking peak identification from the chemstation print out.

To ensure that the degassing procedure did not affect particle size, samples were scanned again with XRD following nitrogen isotherms to check for peak sharpening.
Headspace of a standard mixture of known compounds (benzene, toluene, ethylbenzene, p-xylene) was also injected as a quality control sample to check if peak identification is accurate and reproducible.
2.3 Check the peak width.
The amplification protocol was 50°C for 2 min, 95°C for 10 min, 40 cycles of 95°C for 15 s and 60°C for 1 min. Subsequently, dissociation curves were acquired to check melting peak quality.
