Revised Environmental Monitoring Process and Validation Guide](https://no-cache.hubspot.com/cta/default/2885977/986950a2-0111-48dc-a8cb-1d444e27031d.png)](https://cta-redirect.hubspot.com/cta/redirect/2885977/986950a2-0111-48dc-a8cb-1d444e27031d) Available to [download from Cherwell’s website](https://www.cherwell-labs.co.uk/the-environmental-monitoring-processes-and-validation-guide-landing-page), the new guide has been created following the release of the revised draft of [EU GMP Annex 1](https://www.cherwell-labs.co.uk/eu-gmp-and-annex-1-the-new-version) – Manufacture of Sterile Medicinal Products.  It is intended to assist sterile product manufacturers with reviewing and improving their environmental monitoring (EM) programs in preparation for the proposed changes to Annex 1.  The comprehensive guide highlights the most business-efficient EM measures organisations can take to comply with the latest iteration of the EU GMP Annex 1, and practical steps they can take to create the ideal EM process. It also addresses and summarises the key changes proposed to Annex 1 and covers: Why the EU GMP Annex 1 draft has been proposed; how it helps all industries move closer towards a global standard; how to prepare for compliance; examples of best practice for EM programs and the right tools needed for an effective and compliant program. Andrew Ramage, Cherwell Laboratories’ Microbiology Product Specialist comments: “The draft copy of the new version of EU GMP Annex 1 has considerably more detail on the expectations of designing and implementing an environmental monitoring regime. It remains to be seen how much will change following the public consultation. Regardless of what changes are made, our in-depth guide will help the end user to interpret the new guidelines and to create and implement a robust environmental monitoring regime for their cleanroom, whatever the size of their facility.” With over thirty years’ insight and experience with environmental monitoring applications, Cherwell has intricate insight and expertise that ensures they continually deliver high calibre products and services to their clients.  Their ability to offer bespoke solutions to match customer needs not only applies to their range of [Redipor® prepared media](https://www.cherwell-labs.co.uk/cleanroom-equipment/prepared-culture-media/), but also the [SAS range of air samplers](https://www.cherwell-labs.co.uk/cleanroom-equipment/sas-microbial-monitoring/) and [EM accessories](https://www.cherwell-labs.co.uk/cleanroom-equipment/prepared-culture-media/accessories/) which they specialise in.       Comments ## Read other blog articles [ *By Gill Power* #### Specialist products for boosting microbial EM protocol reliability spotlighted by AnalytiChem UK at Pharmig 2025 ](https://www.cherwell-labs.co.uk/cherwell-labs-post/analytichem-uk-highlight-specialist-em-products-pharmig-2025-annual-conference) [ *By Gill Power* #### New AnalytiChem UK appointment strengthens customer focus and growth strategy ](https://www.cherwell-labs.co.uk/cherwell-labs-post/new-analytichem-uk-appointment-strengthens-customer-focus-and-growth-strategy) [ *By Gill Power* #### Cherwell announces Andy Whittard’s retirement and names Stuart Hall as new Managing Director ](https://www.cherwell-labs.co.uk/cherwell-labs-post/cherwell-announces-andy-whittards-retirement-stuart-hall-named-new-managing-director) ### Sign Up for our Blog We promise that we won't SPAM you. #### What's next #### Recent news [![Specialist products for boosting microbial EM protocol reliability spotlighted by AnalytiChem UK at Pharmig 2025](https://www.cherwell-labs.co.uk/hs-fs/hubfs/Redipor%20TwistLock%20Contact%20Plates%20with%20GS1%20DataMatrix%20Codes.png?width=50&height=50&name=Redipor%20TwistLock%20Contact%20Plates%20with%20GS1%20DataMatrix%20Codes.png) **Specialist products for boosting microbial EM protocol reliability spotlighted by AnalytiChem UK at Pharmig 2025** 10 November 2025 ](https://www.cherwell-labs.co.uk/cherwell-labs-post/analytichem-uk-highlight-specialist-em-products-pharmig-2025-annual-conference) [![New AnalytiChem UK appointment strengthens customer focus and growth strategy](https://www.cherwell-labs.co.uk/hs-fs/hubfs/Tom%20Pickford%20AnalytiChem%20UK%20Business%20Development%20Manager%20Midlands.jpg?width=50&height=50&name=Tom%20Pickford%20AnalytiChem%20UK%20Business%20Development%20Manager%20Midlands.jpg) **New AnalytiChem UK appointment strengthens customer focus and growth strategy** 20 October 2025 ](https://www.cherwell-labs.co.uk/cherwell-labs-post/new-analytichem-uk-appointment-strengthens-customer-focus-and-growth-strategy) #### Subscribe Receive the latest articles as they are published. #### Contact us Registered Office 7 & 8 Launton Business Centre, Murdock Road, Bicester, OX26 4XB **Phone** Tel: +44 (0) 1869 355 500 **Email** [sales.uk@analytichem.com](mailto:sales.uk@analytichem.com)    ![analytichem_Logo+claim_RGB](https://www.cherwell-labs.co.uk/hs-fs/hubfs/analytichem_Logo+claim_RGB.png?width=2000&height=431&name=analytichem_Logo+claim_RGB.png "analytichem_Logo+claim_RGB") ![BSI-ISO-9001-Certified-50px](https://www.cherwell-labs.co.uk/hs-fs/hubfs/BSI-ISO-9001-Certified-50px.png?width=130&height=77&name=BSI-ISO-9001-Certified-50px.png "BSI-ISO-9001-Certified-50px") AnalytiChem UK ©2025 (Formerly Cherwell) Reg. in England No: 01159518 VAT Reg.
