Overview of Restek’s EZGC Online Tools
New Pro EZGC Chromatogram Modeler
This new and improved version of our popular EZGC chromatogram modeler for polymer capillary columns is just as simple to use as the original, but it has been updated and now offers advanced options that give you more control. Based on user feedback, the new Pro EZGC chromatogram modeler lets you do the following:
• Start with either the column you have or a column recommended by the program.
• Select compounds from our libraries or bring your own list.
• Target specific compounds for resolution.
• Alter the GC conditions to optimize your model quickly and easily.
• Repeatedly refine the temperature program.
• Switch carrier gases.
• Change the control method (constant flow, pressure, or linear velocity).
• View elution temperatures in the peak list.
• See results for multiple phases.
EZGC Method Translator and Flow Calculator
The EZGC method translator and flow calculator tools make it simple to switch carrier gases, change column dimensions or control parameters, or to optimize a method for speed or efficiency. Simply enter your method specifications and the program will return a full set of calculated method conditions that will provide similar chromatography. Use the EZGC method translator and flow calculator tool to optimize your analysis for speed so you can increase sample throughput!
Simplify maintenance with the latest LC accessories from Restek. Reusable EXP2 HPLC/UHPLC fittings allow repeated 20,000+ psi seals to be easily made without wrenches. The patented titanium/PEEK ferrule provides zero-dead-volume connections without compromising high-pressure seals. Their compact design makes them perfect for tight spaces, such as small oven compartments and six-port injection valves. In addition, Restek now offers Opti-Max check valves, which provide exceptional performance and reliability while being easy to install and replace. Opti-Max check valves feature Free-Turn housings, which allow the valve to be removed with the tubing still attached, making maintenance fast and reducing fitting wear. Opti-Max check valves are made using rugged stainless steel cartridge bodies with a ceramic ball and seat to ensure longevity in harsh acetonitrile environments.

Troublesome pesticides can be analyzed more easily and accurately with single-compound standards from Restek. New individual standards are now available for dicofol, metribuzin, bromacil, lenacil, dodine, anilazine, captan, and folpet. Use these standards to simplify method development, establish instrument detection limits (IDLs), verify performance, test stability, and resolve degradation issues. Restek is your one-stop shop for accurate, reliable pesticides analysis. We are the only reference standard provider that offers everything you need from sample prep to LC and GC columns and consumables.
Low-level detection of carbon monoxide (CO) and carbon dioxide (CO2) is critical for many applications. Restek’s methanizer (CH4izer) for Agilent GCs allows ppb-level determination of CO and CO2 using a cost-effective FID instead of more expensive instrumentation. The methanizer is factory set to 380 °C to ensure efficient and complete conversion of CO and CO2 to CH4, but the operator can easily adjust the temperature as desired with the touch of a button. This unit controls temperatures precisely and reliably to within ± 1 °C of the defined set point and the actual temperature is shown in real time on an easy-to-read display. The Restek methanizer is less cumbersome than other models and is designed for easy installation and fast catalyst tube replacement so you spend more time analyzing samples and less time on maintenance.

As part of our commitment to the emerging industry of medical cannabis analysis, Restek has expanded its selection of cannabinoid-related reference standards by adding cannabidiolic acid (CBDA). This 1,000 ppm standard is DEA-exempted, so there’s no need to purchase costly neat materials or to make your own standards, and it is prepared in acetonitrile, which helps maintain stability by preventing methylation of the carboxylic acid group on the molecule. Paired with Restek’s THC standards, it is perfect for the analysis of both neutrals and acids in cannabis products by LC and is a must for accurate quantification in medical cannabis potency testing and strain ID. Restek’s CBDA standard is also a certified reference material (CRM) so you know that it meets strict ISO quality requirements.
From potency to pesticides analysis, Restek offers the LC and GC chromatography columns, CRMs, accessories, and sample prep supplies—as well as technical literature and support—needed for accurate, reliable medical marijuana analysis.
