Calibrating for toxic gases at the parts per billion (PPB) level is a critical requirement in various industries, from environmental monitoring to industrial safety. Achieving this level of precision and accuracy demands specialised equipment that can meet stringent calibration standards. One such solution is the ACD gas generator with a microcell, certified down to 50 PPB. This advanced technology offers several advantages over traditional calibration methods and is available for a wide range of toxic gases, including chlorine, hydrogen sulphide, hydrogen cyanide, hydrogen, and nitrogen dioxide. 

Eliminating Cylinder Storage and Reducing Costs – The Green Solution

One of the primary benefits of using an ACD gas generator with a microcell for PPB-level calibration is the elimination of cylinder storage and considerable cost savings. Traditional calibration methods often involve storing and handling gas cylinders, which can be cumbersome, expensive, and potentially hazardous. In contrast, the ACD gas generator generates gas on-demand from a liquid source, eliminating the need for cylinder storage and associated safety concerns. This not only enhances workplace safety but also significantly reduces operational costs.

No Inherent Shelf Life

Gas Cylinders have limited shelf lives, and their quality can deteriorate over time. This presents challenges for maintaining consistent calibration levels, particularly when dealing with PPB-level concentrations. In contrast, ACD gas generators do not have inherent shelf lives, ensuring that the calibration gas produced remains accurate and reliable over extended periods. This feature is crucial for applications that require long-term precision and stability in calibration.

Certified to NIST Standards

Achieving reliable and accurate PPB-level calibration is contingent on meeting internationally recognized calibration standards. ACD gas generators are certified to the National Institute of Standards and Technology (NIST) standard, assuring users of their precision and traceability. Calibration based on NIST standards provides confidence in the accuracy of the generated gas, a critical requirement in industries where safety and regulatory compliance are paramount.

User-Friendly Calibration

Calibrating with an ACD gas generator is straightforward and user-friendly. Operators can simply dial in the required parts per million (PPM) or PPB level, ranging from 5 PPM to 50 PPB, based on their specific calibration needs. This flexibility allows for precision and adaptability, ensuring that the generated gas matches the required calibration levels accurately.

Ease of Shipping and Storage

Gas cylinders, due to their size and weight, can pose challenges in shipping and storage. ACD gas generators offer a more practical solution. They are compact, lightweight, and easy to transport, you can even carry them on planes, making them convenient for both shipping and storage. This streamlined approach simplifies logistics and minimizes the associated costs and hassles.

In conclusion, calibrating for toxic gases at the PPB level demands high-precision equipment that can meet stringent calibration standards. The ACD gas generator with a microcell, certified to 50 PPB, offers an efficient, cost-effective, and safe solution. With no cylinder storage, no inherent shelf life, NIST certification, user-friendly calibration, and ease of shipping and storage, it provides the accuracy and reliability required for critical applications in various industries. By adopting this advanced technology, organizations can ensure the precision and consistency of their gas calibration processes while reducing operational costs and enhancing safety.
