To reduce batch contamination and product loss, you must use an effective H2S (Hydrogen
Sulfide) for purification of CO2. Especially important in the food and beverage markets, pure
CO2 protects your products from the risk of contamination by sulfur compounds, aromatic
hydrocarbons, aldehydes and potentially harmful submicron particle contamination and
bacteria. These contaminants may cause off-flavors and spoilage problems that can quickly
translate into product and dollar loss.

You may not now be adequately protected. Sophisticated quality testing equipment has
shown that the commonly used activated carbon filters do not always effectively achieve the
high quality gas as recommended in the ISBT CO2 Guidelines.

However, you can achieve this high level of purity when using a Sulfur Guard™ filter that
incorporates a unique combination of adsorbents to remove the contaminants from CO2 that
most threaten food and beverage quality. The use of effective, economical filtration media
specifically designed for CO2 will help ensure that your product is protected from these
contaminants. Below is an example of our typical five stage system that we use to to purify
CO2 in beverage plants.
