peak finding was done by the analysis of the second and fourth derivatives of the digital data, coupled with the available knowledge of infrared spectroscopy of silica-water interaction in the investigated range. peak separation was accomplished by curve fitting with four different models. the model...

By measuring the IR peak areas of the adsorbates on the sorbent in contact with the gas mixture, the actual amounts of the sorbate can be determined. The method is fairly simple, quick, and accurate even at low concentrations provided the adsorbates exhibit strong distinct peaks and the ...
ftir分析方法（FTIRanalysismethod）ftir分析方法（FTIR analysis method）Two, group frequency and characteristic absorption peak Each molecule of the constituent molecule has its specific infrared absorption region. According to the nature of chemical bond, which can be divided into four regions: 4000 - ...
Peak shifts were seen in the adsorbed layer FTIR spectrum that match those observed when PNIPAM solution is heated above its LCST. This observation indicates that adsorption causes a conformational re-arrangement similar to that seen when PNIPAM undergoes a coil-to-globule transition, in this case ...
The quantitative analysis was conducted via an ad-hoc calibration curve (peak height vs concentration) created using six standard solutions of ethylene glycol in water (concentration range of 0.2–5%wt). For both salutes, loads in the LOS were estimated by multiplying the calculated water load ...
