In the absence of light, biomass production is driven by chemical energy through microbial chemosynthesis. H2, a potent reductant capable of supporting chemosynthesis, is readily generated by reactions between iron and silicate minerals and water. Here, we show that lithogenic H2 produced by glacial comminution of iron- and silica-rich basaltic bedrock supports microbial chemosynthesis
Additives are absolutely essential in the development of commercial polymeric materials. Accordingly, an exhaustive control of composition and evolution in these additives over time is necessary to validate their performance and safety during their shelf life and, consequently, their ultimate applications. Gas chromatography coupled with mass spectrometry, GC–MS, is described in the present
Chamaecyparis obtusa (CO) belongs to the Cupressaceae family, and it is found widely distributed in Japan and Korea. In this study, the anti-proliferative activities of the methanol and water extracts of CO leaves against a human colorectal cancer cell line (HCT116) were investigated. The methanol extract of CO leaves, at a concentration of 1.25 µg/mL, exhibited anti-proliferative activity
For instance, DWK Life Sciences announced earlier this month that it was expanding and modernizing its facility in Tennessee to double production capacity for its borosilicate glass vials.
Ethanedinitrile (EDN) shows potential for controlling stored product pests, and limited studies point to its insecticidal activity against a wide range of stored product pests (Hooper et al. 2003). EDN, also known as cyanogen and oxalonitrile, has the molecular formula (CN) 2 (also as C 2 N 2 ) and is a colorless gas with an almond like odor.
Any vial with a secure gasket seal should suffice, and 20‐mL Wheaton scintillation vials with cone cap liners work well. For best results, the fixed buds should occupy no more than 50% of a full vial of fixative.
The supernatant was moved to a glass scintillation vial (DWK, Life Sciences, Millville, NJ), neutralized with 3 mol/L KOH, and 15 mL of scintillation fluid was added.
GC oven temperature started at 110 C for 4 min, rising to 230 C at 3 C/min and to 280 C at 20 C /min with a final hold at this temperature for 2 min. GC flow rate with helium carrier gas were 50 cm/s. The GC column used was a 20 m x 0.25 mm x 0.25 mm Rxi
Vitamin E acetate (VEA) has recently been identified as a potential chemical of concern in the investigation of e-cigarette, or vaping, product use associated lung injury (EVALI). According to the Centers for Disease Control and Prevention (CDC), most patients report a history of using tetrahydrocannabinol (THC)-containing e-cigarette or vaping products; approximately 50% of the THC
With thousands of combinations to choose from, DWK Life Sciences offers the largest and most diverse selection of chromatography lab vial solutions and microplates. Our ISO 9001 facility manufactures vials that meet or exceed OEM specifications for headspace, routine HPLC/GC use,

I don't know if the procedure is different in Chrom 6.8 (except that 'backup' is called 'export' in your version) but apparently this is how you backup data in Chrom 7:
