Ammonia Sampler Improves Sampling Safety and Accuracy

New design features offer a solution for common challenges associated with manual sampling.


Swagelok (Solon, OH) has announced the release of the Swagelok ammonia sampler. This innovative offering makes anhydrous ammonia sampling safer by minimizing operators’ exposure to liquid and vaporized ammonia. It also introduces consistency into the sampling operation, significantly expedites the sampling process, and eliminates the need to transport ammonia samples within the facility.

Anhydrous ammonia is used in the production of fertilizers, plastics, textiles, petroleum, and more. To avoid ammonia stress corrosion cracking in storage tanks and product quality concerns, the product must be regularly sampled to verify a water content of 0.2% to 0.5%. The Swagelok ammonia sampler has been specifically designed to address the issues inherent to manual sampling by utilizing:

  • Closed-sample fixtures that improve safety by limiting operator exposure and minimizing environmental impact from excess emissions.
  • Residue tubes that are pre-chilled using the cold ammonia itself, thus preventing aggressive boiling that threatens fill accuracy.
  • Features that help to control the dispensing of the ammonia sample and ensure a consistent sample size.
  • A single handle for easier operation and reduced operator error.
  • A touchscreen interface to control all heater operations.
