In this instalment of “Concerns of Excellent” the producing of a user requirements specification (URS) for the two a liquid chromatograph process and CDS software package is discussed.

It is important to know that the contents within a URS usually are not static. As your chromatographic requirements modify so as well may your CDS and chromatograph requirements. As a simple example, Should your UV detector is experienced amongst 210 nm and 280 nm along with a new analyte process has detection at 310 nm, then you need to update the instrument specification and requalify the detector.

As we tactic International more info Women of all ages’s Day 2025, this yr’s topic highlights the value of accelerating action. ISPE’s Women of all ages in Pharma® embodies these concepts by making a platform for connection, progress, and empowerment.

The URS ought to be modifiable, but changes need to be beneath a formal Manage course of action. The simplest is by up-versioning and authorising the new edition then archiving the outdated document.

Except alterations are wanted for certain element assessments, the OQ need to be executed utilizing the program configuration click here which will be used for routine analysis.

Nevertheless, I don’t prefer to disappoint you, so here are the standard conventional requirements and pharmaceutical polices you might have to consider.

Hence, composing the URS for an analytical instrument is a very different exercise than the design qualification (DQ) period or selecting the instrument and supplier.

If main breakdown occurred while in the instrument/ equipment or significant element is replaced from the instrument/ machines like motherboard, Processing board or detector, go away IQ section and fill the MP section and re-qualify the instrument/ machines.
