“…In this method, a sample with an analyte content of CS 0 is placed in a vial (stage I), where the analyte passes to the gas phase according to the partition coefficient K = CS/CG at a set temperature (stage II). The gas phase is taken for chromatographic analysis using a syringe (stage III) or a dosing loop [12,13]. The principle of the headspace method is illustrated in Figure 1.…”

Abstract.Headspace technique and gas chromatography method with mas detector has been used for the determination of volatile organic compounds (VOC) emitted from various building and finishing materials, such as sealing foams, mounting strips, paints, varnishes, floor coverings. The tests were carried out for different temperatures (in the temperature range of 60 to 180 °C) and the time of heated vials with tested materials inside. These tests were conducted to verify the possibility of use this method of determination the VOC emission. Interpretation of chromatograms and mass spectra allowed to identify the type of compounds emitted from the tested materials and the optimum time and temperature for each type of material was determined. The increase in heating temperature of the samples resulted in increase the type and number of identified compounds: for four materials the increase was in the whole temperature range, for others it was from 90 °C. On the other hand, emission from mineral wool was low in whole temperature range. 30-minutes heating of the samples was sufficient to identify emitted compounds for most of tested materials. Applying a longer time, i.e. 24 hours, significantly increased the sensitivity of the method.

“…Headspace is based on the analysis of the gas phase in equilibrium with the condensed phase [12][13][14][15]. That method has many uses, in particular for complex matrix samples, such as environmental and biological samples [14][15][16].…”

“…This technique is based on a dynamic process of adsorption of volatiles on the vapor phase in the sample headspace in a silica fiber coated with an adsorbent polymer and has high sensitivity in the volatiles extraction with a wide range of polarity (BICCHI et al 2008). In the static headspace sampling techniques (S-HS), the equilibrium between the sample and the headspace gas phase must be reached, and a gaseous fraction of the headspace is collected directly for analysis by gas chromatograph (SNOW & SLACK, 2002;WANG et al, 2008). The S-HS technique is simpler and faster and has been used in comparative analysis of the flavor profile of vegetable matrices (MILLER & STUART, 1999;VARMING et al, 2004;BYLAITE &MEYER, 2006;UBEDA et al 2011).…”

“…A fraction of the headspace vapor is sampled and introduced into a GC system. Injection of the analytes evaporated from the sample into the GC system could minimize the contamination of the GC instrument and deterioration of the GC capillary column [3][4][5][6][7][8][9]. A comprehensive analytical procedure using HS-GC for residual solvents in drug substances and drug products is described in the United States Pharmacopeia 37 (USP 37) [10].…”

A simple, rapid, accurate, precise headspace gas chromatographic (HS-GC) method was developed and validated for simultaneous quantitation of organic volatile impurities (residual solvents) in technical-grade active ingredients (TGAIs) of pesticides and agrochemicals. The HS-GC method utilizes conventional capillary columns. The HS-GC operating conditions were optimized, and 18 organic volatile impurities were efficiently separated. The versatility of the method was confirmed in terms of validation characteristics of specificity, limit of quantitation, linearity, accuracy, and precision. The proposed method was successfully applied to the analysis of pesticide and agrochemical TGAIs.
