“…5,14 Relationships between Kováts indices and thermodynamic properties are used for determination of vapor pressures, enthalpies, and entropies of adsorption and vaporization of different analytes. [15][16][17][18][19][20][21][22][23][24][25][26][27][28] Zabiegala et al 29 employed retention indices for the estimation of the calibration constants of permeation passive samplers with polydimethylsiloxane membranes. RI is also used as an aid in the development of new medical and perfume formulations.…”

Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl silicone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals. V

“…The reported vapour pressure data for pyrene in the range of 50 -150 °C provided a useful guide for assessing pyrene's suitability as a fingermark reagent [25,26]. This study commenced with an evaluation in the range of 25 -75 °C, as milder conditions may have wider applicability for fragile evidence types.…”

“…Many of these, as well as more recent studies looking at biochar [23], were undertaken to assess the environmental impact that results from the release of pyrene. The enthalpy of sublimation for pyrene has been measured at 103.25 ± 2.05 kJ/mol -1 [24], and the vapour pressure of pyrene measured between 50 -150 °C [25,26]. These values provide a useful guide for optimising the temperature range when assessing the volatility of pyrene as part of a fuming study.…”

Volatilised pyrene: A phase 1 study demonstrating a new method of visualising fingermarks with comparisons to iodine fuming

Pyrene is a fluorescent polycyclic aromatic hydrocarbon that can be volatilised under mild conditions. When fumed, pyrene is rapidly absorbed into the sebaceous residues of fingermarks, enabling their fluorescent visualisation upon excitation with ultraviolet radiation. This new means of fluorescent fingermark detection is more sensitive than the non-fluorescent iodine fuming approach for nonporous surfaces. This is demonstrated here in a phase 1 study using split-print comparisons on metal and glass surfaces. Pyrene-treated fingermarks also retain the volatile fluorophore for comparably long time periods relative to iodine fuming (in the order of hours). The phase 1 study comprised four donors, and 80 natural fingermarks that were grouped into two time periods; aged 24 hours and 1 week. Iodine fuming was chosen as a reference to showcase the effectiveness of pyrene given it is the most closely-related chemical fuming method in routine use. This study demonstrates that pyrene fuming increases the quantity and quality of fingermark visualisations relative to iodine fuming, and is free of many of the latter method's drawbacks. Preliminary results shown here also show the effectiveness of pyrene fuming on highly patterned surfaces, and its compatibility with the use of gelatine lifters. Pyrene fuming is thus easy to effect, low-cost, and shows great promise as a new means of visualising fingermarks on non-porous surfaces.
