Water Testing

Purified water is a key component in the manufacturing of virtually all pharmaceutical products. Water purification systems must be validated to ensure that the specified quality of water is consistently produced.

ALS provides a complete service for water testing in the Pharmaceutical and Healthcare and industries. We provide pharmacopoeial analysis of highly purified water, purified water, water for injection (WFI), in addition to water from steam sterilisers and washer disinfectors. Testing can be undertaken to various standards and guidelines including CFPP01-06, CFPP01-01 Parts C and D, HTM 2030 & 2031, EN285.
