“…In recent years, subcritical water (SC water) has been widely applied to various processes such as organic synthesis (Holliday et al, 1998), organic extraction (Miller and Hawthorne, 1998;Yang et al, 1998;Ozela et al, 2003), decomposition of stable toxic organic wastes (Goto et al, 1997;Hashimoto et al, 2004), etc.…”

“…This technique has been successfully applied to the extraction of dioxin (Hashimoto et al, 2004), pesticide (Richter et al, 2003) and PAHs (Dadkhah and Akgerman, 2002) from contaminated soils. The use of SC water for the extraction of essential oils from natural products has also been proposed (Ozela et al, 2003). Thus far, many studies on the application of SC water have focused on organic substances, but less information is available on inorganic waste processing.…”

“…The studies to observe this effect were performed at a DTD temperature of 1508C. In earlier studies, Ozel et al [18] reported that the optimum temperature of DTD was 1508C for the volatiles of Pistacia vera L. They reported that some components which were not the components of essential oils of Pistacia vera L. appeared at higher temperatures of 200 and 2508C. Although, the artifact formation was not particularly followed at the various desorption temperatures, hydrogen sulphide was not reported when the desorption temperature was below 1508C but increased dramatically at 200 and 2508C.…”

“…GC6GC has been used by Marriott et al [17] and by Ozel et al [18] for essential oils and by Arora et al [12] for cheese. The use of a mass spectrometer is highly desirable for identification of the numerous separated compounds found during a GC6GC run.…”

Analysis of the volatile components of Cheddar cheese by direct thermal desorption-GC6GC-TOF/MSVolatile compounds were isolated from Cheddar cheese using direct thermal desorption (DTD) and analysed using comprehensive 2-D GC (GC6GC) coupled with TOF MS (TOF/MS). In total 12 aldehydes, 13 acids, 13 ketones, 5 alcohols, 3 hydrocarbons and 9 miscellaneous compounds were identified at desorption temperatures of 100, 150, 200 and 2508C using mature Cheddar cheese. A temperature of 1508C was found to be optimum for the DTD of volatiles from mature Cheddar cheese. The major components were acetic acid, butanoic acid, 3-hydroxy-2-butanone and 2,3-butanediol. A DTD temperature of 1508C was used to observe the effect of maturation (mild, medium or mature) on the volatiles of Cheddar cheese. The major components of the volatiles of mild, medium and mature Cheddar cheese were almost the same. However, their percentage compositions were found to change with the stage of maturity. DTD is simple, fast and requires only a small amount of sample (approximately 10 mg) and works well with comprehensive GC6GC-TOF/MS. Comprehensive GC also separated a number of components which remained overlapped on the single column, such as octane and hexanal.

Subcritical water chromatography (SBWC) refers to a new reversed‐phase liquid chromatography (RPLC) technique where high‐temperature water is used as the sole mobile phase component. The major advantage of SBWC is the elimination of toxic mobile phase organic solvents required in traditional RPLC. These organic solvents are not only expensive in terms of purchasing price but also costly in their waste disposal. Therefore, the SBWC technique offers both economical and environmental benefits. Additional advantages of SBWC are fast analysis time; temperature‐dependent efficiency, selectivity, and resolution; temperature‐programmed elution; and ability to accommodate both gas‐ and liquid‐phase detectors. Most importantly, after years of academic studies, industry started paying attention to this economical and green separation technique. For example, Procter & Gamble has recently funded an SBWC project in developing green SBWC methods for the analysis of skincare products.
