All certified reference materials supplied by Gasco are manufactured using traceable weights and measures before being analyzed or tested by specific, documented methods, and come with a certificate stating the method(s) used.
These methods exist to promote similar product quality and properties for a single product type from various manufacturers or to ensure a minimum product quality. Methods may be nationally or internationally recognized, such as those from ASTM, ISO, or US EPA.
Traceability is demonstrated by an unbroken chain of measurements or calibrations all the way to the accepted international primary reference materials. This means the calibration of the instrumentation involved throughout the manufacturing process (scales/balances, mass flow controllers, pressure gauges, etc.) be ISO17025 certified. Calibration certificates for relative instruments are kept on file and referred to on the mixture certificate if required.
To meet them most stringent of customer requirements some mixtures will have been produced or calibrated within the scope of an ISO17034 or ISO17025 accredited organization whose accreditation is recognized under EC or the ILAC MRA, so they are accepted globally.
Accreditation proves the producer’s technical capability in measurement, and stated traceability to SI units, having been thoroughly assessed by the relevant national testing authority.
These mixtures meet the requirements of:
ISO/IEC17025:2017
ISO Guide 30:2015 (Clause 2.1.1 or 2.1.2)
AS2290:2018
Light liquid hydrocarbons, sometimes referred to as liquified gas mixtures, are mostly known to fit between what can easily be distinguished as crude oil product, or natural gas streams. Light liquids fit a broad spectrum of process conditions spanning from NGLs, LPGs, condensates, Petrochemical, and Refinery Gases.
They are available in a range cylinder including constant pressure (CPC) and standard gas cylinders fitted with dip tube valves which can ensure the composition of the standard remains homogenous by keeping it under pressure.
Light liquid hydrocarbon reference materials have the advantage of closely matching the product being analyzed, while also offering increased efficiency by allowing an increased number of calibrations with the same cylinder, when compared to a gaseous mixture.
GASCO provides a wide variety of liquid reference materials / calibration standards from DCG partnerships. These standards are gravimetrically prepared and N.I.S.T. Traceable by weight with the gravimetric values verified by one or more analytical methods.
ASTM compliant and ISO17034 Liquid Standards in bottles and ampoules.
Available in 1 mL, 2 mL, 5 mL, 10 mL, 20 mL, 50 mL, 100 mL, 200 mL, 500 mL ,and 1 liter sizes.
We offer a full line of high precision gas control equipment alongwith our MICRO300 Precision Regulator. All items are kept in stockfor fast shipment.
The MICRO300 Precision Regulator, specially configured by GASCO Gas & Instrumentation for highly-sensitive applications, is designed for customers who need the most accurate calibrations.
The MICRO300 features fully supported ‘sensitive’ pistons and a low internal volume to reduce wasted gas and minimise reactions. The regulatoris availablewith orwithout SilcoNert® 2000 coating.

GASCO supplies a complete line of flow and pressure regulators
for non-refillable and high-pressure cylinders to supply specialty
gas standards and calibration gases.
GASCO’s flow regulators include the Fixed Flow (FF), On Demand Flow (ODFR) and Variable Flow (VAF) regulators used for calibration and gas supply to gas analyzers and gas detection instrumentation. The Tech-Master, Spec-Master and Chem-Master pressure regulators are
part of a line of products including manifolds and outlet points to provide a complete gas control solution. The product line is a resistant to non-corrosive and corrosive gases up to n6 purity.
Whether gas chromatography, process gas analyzers, environmental analysis, or gas detection we have the regulator systems to meet your gas handling requirements.
