6.5.2.2 Gases - To prepare standards for any of the six halocarbons that boil below 30 °C (bromomethane, chloroethane, chloromethane, dichlorodifluoromethane, trichlorofluoromethane, vinyl chloride), fill a 5-mL valved gas-tight syringe with the reference standard to the 5.0-mL mark.
The kinetic of reduction of 2-heptanone by samarium iodide in the presence of hexamethylphosphoramide has been analyzed by gas chromatography (GC). Application. 2-Heptanone has been used as a standard odorous compound in a study to understand the odor responses in basiconic, intermediate and trichoid olfactory receptor neurons of Drosophila

(6,7), and high-performance liquid chromatography (HPLC) (8–11) methods for the quantitative determination of PTX in biological sa mples have been reported.
The peak homogeneity of HPLC and GC as well CE and SFC responses can be shown by using a mass spectrometer as a specific detector. The constancy of the mass spec trum of the eluting peak with time is a demonstration of homogeneity, albeit not easily quantified [22].
GC analysis is carried out using a PoraBOND U column (Varian, 25 m, 0.32 mm i.d., 7 μ m film) with a flow rate of 2 ml/min with detection utilizing the SIM capability of the MS. The column temperature is held at 40°C for 12 min to allow residual water to pass into the MS and be pumped away.

Deactivated Wide Opening Screw Top Glass Vials These wide opening 2 mL, 12 x 32 mm vials are created using a deactivation process to eliminate sample interactions. Ready-to-use for the analysis of polar compounds such as phenols, proteins, antibodies, amines, metabolites, herbicides and pesticides.
Some utilize robotic arms to pick up a sample vial; some use tray rotation while others move the sampling needle to the respective vial coordinates. The dimensions of autosampler vials vary. Most autosamplers are equipped with trays that use 12x32mm vial configurations but some like the Waters Wisp require a 15x45mm configuration.
Vial for GC/HPLC 2ml Polypropylene Micro Vials ND9 + ND11 2ml Polypropylene vials are available in 300 ul volumes. Breakage is not an issue with PP vials and they are not reactive with most sample chemistries.
Jan 01, 2008 · Laboratory centrifuges usually work with 20–40 cm diameter rotors holding 10–100 sample vials or two to four microtiter plates. Efficiency depends on rotational velocity; typical laboratory centrifuges work with 100–20,000 rotations per minute, allowing separations in a few minutes time.
