DB WAX UI Column Brochure Increase Your Analytical Confidence For Challenging Polar Compounds Agilent J&W DB-WAX Ultra Inert GC columns Now You Can Achieve Better Peak Shape and Reproducibility for Challenging Polar Compounds GC columns with polyethylene glycol (PEG) stationary phases are commonly used for analyzing compounds with polar functional groups. They are well suited for food, flavor, and fragrance applications, as well as industrial chemical analysis in quality control and method development labs. For active and complex polar compounds, you cannot afford adsorption caused by flow path activity. Having to repeat or verify suspect analyses wastes valuable resources, hinders productivity, and hurts your bottom line. Unreliable results can also have serious implications in the quality of the foods we eat—and the products that consumers and businesses use every day. Perform worry-free analysis of polar – Implement easily, with minimal workflow compounds with NEW Agilent J&W interruption: DB-WAX UI GC columns have DB-WAX Ultra Inert GC columns the same selectivity as DB-WAX GC columns. This capability makes upgrading to Ultra Inert With their Durabond polyethylene glycol stationary performance easy, with minimal validation. phase and proprietary processing, DB-WAX Ultra What’s more, there’s no need to recreate or Inert GC columns deliver excellent inertness with modify existing compound libraries that are greater sensitivity than any other WAX column on based on DB-WAX selectivity. the market. These innovative columns let you: – Spend less time on troubleshooting and reruns: With DB-WAX UI GC columns, you can count on excellent peak shape and column-to-column inertness reproducibility, as well as retention time stability. – Save money on columns and maintenance: DB-WAX UI has extended inertness lifetime that withstands repeated temperature cycling to the upper temperature limits of the column. – Stop wasting time prequalifying columns: Specific inertness testing during quality control guarantees out-of-the-box inertness performance for every DB-WAX UI column. 2 Trust Ultra Inert GC columns for your trace-level analysis of active analytes DB-WAX UI GC columns are part of the Agilent J&W Ultra Inert GC column family, which pushes industry standards for consistent column inertness. Every Ultra Inert GC column is rigorously tested to ensure optimal active analyte delivery to the GC or MS detector. The result: optimal, lower detection limits and more accurate identification of challenging polar analytes.

  • Retention Indices for Frequently Reported Compounds of Plant Essential Oils
    Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) 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 sili- cone 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.

  • Visible-Light-Driven Photooxidation of Alcohols Using Surface-Doped Graphitic Carbon Nitride
    Electronic Supplementary Material (ESI) for Green Chemistry. This journal is © The Royal Society of Chemistry 2017 Visible-Light-Driven Photooxidation of alcohols using surface-doped graphitic carbon nitride Wuyuan Zhang, Anna Bariotaki, Ioulia Smonou, and Frank Hollmann* Material and Methods Materials Unless stated otherwise all chemicals were purchased from Sigma-Aldrich, Fluka, Acros or Alfa-Aesar with the highest purity available and used without further treatment. Synthesis of g-C3N4 and carbon nanodots doped (CD-C3N4) The g-C3N4 was synthesized via the simple calcination (Carbolite furnace; CWF 12/5, 2400 W) of urea (10.0 g) at 600 °C for 4 h (5 °C/min), a yellowish powder was obtained after the cooling to room temperature.1 The carbon nanodots were synthesized via the thermal decomposition of sucrose with slight modification.2 Briefly, 0.75 g of sucrose was dissolved in 30 mL of MilliQ water and stirred at room temperature for 0.5 h. The solution was transferred into a 45 mL Teflon-lined stainless steel autoclave reactor, and heated at 180 °C for 5 h (10 °C/min). After cooling the reactor to room temperature, a brown mixture was obtained. The mixture was centrifuged (8000 rpm for 20 min), and the pellet was washed with water (3×) and freeze-dried. 3 In order to deposit carbon nanodots to the surface of g-C3N4, Liu et al’s procedures were adopted. Firstly, a stock solution of carbon nanodots (1 mg in 25mL water) was prepared. 15.0 mL of this stock solution was mixed with 15.0 mL of NH4OH (28 %) and sealed in a 45 mL Teflon-lined autoclave reactor.

ABSTRACT Oxidation of 4-Methoxybenzyl alcohol by different Cr (VI) oxidants [PDC and PCC] has been studied in acetic acid-H2O medium in the presence of PTSA spectrophotometrically. The reactions are found first order with respect to both the oxidants, [H+], and [substrate].Michaelis-Menten type kinetics is observed. The reaction rate decreases with increasing volume percentage of acetic acid in reaction mixture. The reaction was studied at different temperature [298-318 K] and activation parameters were computed. The oxidation product was identified as Cr (III) and corresponding aldehyde. The oxidation rate order was found with respect to the oxidants are: PCC > PDC KEYWORDS Oxidation, 4-Methoxybenzyl alcohol, PTSA, PCC and PDC. 1.
