Accurate gas calibration for quality control in beverage production!

Millions of beverages are sold worldwide every day. Testing contaminates that can be found in beverage products is a must to ensure a safe product. The quality and purity of the drink falls on all those involved in the supply chain from the simple components to the factory that bottles the beverage. Any failures in quality control can lead to health concerns for consumers and major recalls.

There are a few points in the supply chain where contamination can take place. One major gas used in the beverage industry is Carbon dioxide, (CO₂). CO₂ gas is used to carbonate drinks, is produced during fermentation, used to blanket a beverage (such as wine) to preserve taste and color, and other uses.

Contaminants in beverage can be traced to:

• CO₂ gas source,
• Byproducts of fermentation
• Reaction between air and the beverage

Some trace contaminants, are Hydrogen sulfide (H₂S) (among other sulfurs), VOCs, and ABETX.

Calibration for trace contaminates in CO₂ requires accurate gas standards that are reliable and repeatable. 

KIN-TEK offers many solutions to calibrate gas analytical equipment used to identify trace concentration contaminants. The FlexStream™ multi-modular permeation system using Trace Source™ permeation tubes provides trace levels of gas standards for verifying contaminant concentrations present in CO₂ or other gas streams.

Combining different FlexStream™ modules in a series creates an application specific system. For example, the addition of a Interface Module, allows the user to pressurize the Span Gas sample to simulate the headspace environment found inside a carbonated container. Data recording, automation, and remote user interface are all features of the FlexStream™ permeation system that simplify user interface.

Calibration for Humid Conditions

Gas analyzer or detector calibration is more effective when the gas standard closely matches conditions of analysis. Percent relative humidity (%RH) in the environment can affect analytical readings as well as contaminate or shorten the lifespan of the detector. To be sure you are calibrating to the same conditions as exposure, you need to create calibration gas that relates to the operational environment.

KIN-TEK Analytical, Inc. offers the FlexStream^TM Base Module paired with the FlexStream^TM Humidified Gas Module as a solution for dynamically creating variable %RH from 30% to 90% (depending on the application) for accurate calibration of gas analytical and detection devices. The FlexSteam^TM System can be operated through FlexLink^TMsoftware (provided) or by local touchscreen integration. Gas standards using selected permeation tubes are created in the FlexStream^TM Base Module and are combined with humidity vapor from the humidified gas module.

The %RH is varied by the ratio of dry to wet gas measured and controlled as it passes an external sensor situated close to the point of detection. System automation controls the %RH to +/- 3% and data is logged to a file. The user can decide between Zero gas %RH or Span gas %RH (with permeation tube gas combined in the gas stream). Comparison studies of detector exposure with and without humidity at different levels are easily done.

Take the guess work out of your gas calibration and put the control at your fingertips. Contact us for a quote today.

Calibration Gas Standards for Food Flavorings and Additives

The health and environmental impacts of food additives and preservatives are becoming more prominent. To ensure that foodstuffs meet quality and regulatory guidelines, proper calibration of analyzers for these additives is required. Among the common additives are flavorings like Vanillin, Eugenol and d-Limonene, Terpenes like α-pinene and β-pinene, and preservatives like benzoic acid. While many standards for foodstuffs are provided in liquids for Liquid Chromatography analysis, KIN-TEK Analytical, Inc. has developed permeation tubes for creating gas standards that are easily quantifiable for calibration of gas chromatographs, GC/MS, or other gas detection devices.

The Trace Source™ Permeation Tube technology is employed in KIN-TEK’s Gas Standard Generators to provide accurate, on-demand calibration standards. Each permeation tube and gas standard generator include a Calibration Certificate traceable to the National Institute of Standards and Technology (NIST). KIN-TEK delivers trace gas calibration product solutions and services worldwide and offers over 550 types of chemical gas standards.

Gas Standards for Chemical Warfare Agent (CWA) Simulants

Recent world events have reinforced the need for accurate detection and analysis of trace concentration Chemical Warfare Agents (CWAs).

Calibrating analytical devices using real agents is dangerous and difficult so simulants such as Dimethyl methylphosphonate (DMMP) and Diisopropylmethylphosphonate (DIMP) are used as G-agent simulants and Methyl salicylate (MS) and 2-Chloroethyl ethyl sulfide (CEES) are simulants for HD agents.

KIN-TEK Analytical, Inc. offers several CWA simulants for calibrating detectors or researching new methods of rapid detection. Trace Source disposable permeation tubes used within a FlexStream™ Permeation System provide an excellent method for creating high quality gas standards. Dilution of the output gas from the permeation tube provides step changes for creating a calibration curve of different concentrations. Secondary dilution capability with the addition of controlled %RH humidified gas in the right matrix provides the best combination to test for real life detection scenarios that would occur in humid environments.
