    Determination of Additives in Beverages using Ascentis Express Columns

    Beverages, such as sodas and energy drinks, can include a number of polar ingredients, which are easily soluble in the water matrix of the drinks. These ingredients include sweeteners (sugars and sugar substitutes), caffeine, vitamin supplements, amino acids, organic acids, and plant extracts. Because the analytes are already in solution, there is no need for extensive sample preparation. Dilution followed by direct injection into an HPLC is typically suitable. In this article we present two beverage applications using Ascentis Express HPLC columns. Ascentis Express columns offer faster HPLC on any system. One benefit is their ability to produce the resolution, efficiency, and speed on conventional HPLC systems that is associated with the use of sub-2 micron columns on a UHPLC system, without generating high backpressure. Column chemistries (RP-Amide and HILIC) were selected for this article based on their enhanced performance with polar compounds in comparison to C18.

    Increased Pigment Removal with Analysis of Pesticides in Oranges

    An application was developed to demonstrate increased pigment removal for the analysis of pesticides, using Supel™ QuE Z-Sep/C18 QuEChERS and an Ascentis® Express C18 HPLC Column. The improved cleanup can decrease column and instrument fouling, leading to extended LC column lifetime and reduced instrument downtime.

    Baseline® 9100 Residual Solvent Analysis — Ethanol, Isopropanol, and Acetone

    MOCON’s Baseline® Series 9100 Gas Chromatograph equipped with a photoionization detector (PID) provides a quick, cost effective quantitative analysis of IPA and acetone in air at levels in the ppb and sub-ppb range with no preconcentration necessary. Isopropanol and acetone are detected and accurately quantified to sub-ppb levels in under 3 minutes with ethanol producing no interference. The instrument is sensitive to below 5 ppb for both IPA and acetone employing the MOCON Baseline® standard PID or 0.1 ppb using the MOCON Baseline® high sensitivity PID.

    Measurement of ethylene oxide for monitoring workplace exposure limits

    The Series 8900 Ethylene Oxide Analyzer combines the selectivity of gas chromatography with the sensitivity of a Photoionization Detector (PID) providing interference free response to Ethylene Oxide (EtO) at levels below 0.05 ppm. This analytical method is referenced in OSHA`s `Occupational Exposure to Ethylene Oxide: Final Standard` 29 CFR Part 1910. The system documents exposure levels including: time-weighted averages (TWA), short-term exposure limits (STEL) and instantaneous alarms. Areas that are typically monitored include; EtO Sources - gas storage areas, sterilizer doors, aeration doors, and the General Work Area - decontamination, packaging and preparation and sterile product storage areas.

    Measurement of acrylonitrile in ambient air for monitoring workplace exposure limits

    The Series 8900 Acrylonitrile Analyzer provides direct measurement of Acrylonitrile in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits. The Series 8900 Acrylonitrile Analyzer employs a flame ionization detector (FID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Acrylonitrile and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. Acrylonitrile is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

    Analytical instruments for gas chromatography

    Gas Chromatography requires a stable repeatable flow of the carrier gas with negligible temperature drift. The Axetris MFC provides excellent control of the gas flow resulting in sharp peaks and high resolution of the chromatograms. Multiple calibrations allow the control of Helium, Hydrogen or Nitrogen. Due to the high turn down ratio of 1000:1 and more, a broad range of flows can be controlled.
