SulfAlert I™

Total Sulfur Analyzer

To ensure that your bev-grade CO₂ meets ISBT guidelines for Total Sulfur Content (TSC*), ALI offers the SulfAlert I™. This rugged, compact, low-cost analyzer allows you to quickly obtain TSC data as described in ISBT Method 13.0. A reliable mini-reactor, Nickel (Ni) catalyst tube + controlled reactor gas flow (hydrogen at 20 cc/min) are used to convert all sulfur-containing impurities into H₂S. In this reductive mode, a high sensitivity H₂S detector tube (yellow-red/pink color change) is used to accurately determine the TSC present (including: Hydrogen Sulfide, Carbonyl Sulfide [COS], Methyl Mercaptan, Di-Methyl Sulfide + Carbon Disulfide!) down to v low ppb levels! SulfAlert I™ units are ideal for routine, on-site TSC testing, or as a back-ups for expensive / complex electronic sulfur monitors. Both bench-top or rack-mount models are available. The SulfAlert I™ is designed for:

CO₂ Production Facilities - Distribution Depots - Beverage Manufacturing Plants - QC Labs

Easy Installation & Use

A SulfAlert I™ is simply connected to a pressure-regulated (20 psig [140 kPa]) source of vaporized liquid CO₂. A 1/16” Sulfinert passivated transfer line is provided. A pressure-regulated (50 psig, [490 kPa]) low flow source of hydrogen is also connected to the unit. A length of 1/16” ss tubing is available for this purpose. Installation is complete in less than 5 min.

Other TSC instruments that cost 4 - 10X more, use several support gases + vacuum systems+ need complex/costly maintenance, + also require frequent calibration using gas standards or permeation tubes. A SulfAlert I™ does NOT require calibration standards + only requires a clean source of hydrogen (from either a safe, low flow H₂ generator or a small cylinder). The Ni tubes used are designed for long life + simple field replacement. Periodic performance validation checks are easy and rapid to perform.

With a SulfAlert I™, non-technical personnel can obtain accurate Total Sulfur results after minimal training.

Support, Supplies & Service

All SulfAlert I™ Systems include an Operations  + TSC Methods Manual. This literature contains simple instructions + helpful, color pictorial examples. ALI and its worldwide affiliates manage all requests for training, supplies, replacement parts, maintenance/repair + technical service. ALI is a discount distributor of detector tubes and stocks replacement Ni Megawall™ catalyst tubes + other supplies. ALI also offers a special validation standard (low ppm v/v COS in Ar) in small high pressure cylinder (p/n COS-Val1) + passivated connective hardware (p/n CAL-GAS Kit).
