Solvent recovery system SRS 100i

for the pharmaceutical industry

Overview
The Sample Recovery System™ SRS 100i delivers a controlled, standardised approach to drug recovery in OINDP testing, reducing variability and supporting consistent traceable results across both Delivered Dose Uniformity (DDU) and Aerodynamic Particle Size Distribution (APSD) workflows. The system automates key stages of sample recovery to produce HPLC-ready samples for immediate analysis. Patent Pending.

Product summary
The SRS 100i automates solvent dispensing, dissolution/agitation and sample collection from test components such as impactor stages, DUSA collection tubes, induction ports and preseparators. By replacing manual recovery steps with a defined automated workflow the system reduces analyst-to-analyst and site-to-site variability, reduces manual handling time, and minimises the risk of cross-contamination.

Key features

• Reproducible drug recovery across analysts and sites
• Controlled solvent dispensing and dissolution
• Reduced manual handling and hands-on recovery time
• HPLC-ready samples for immediate analysis
• Configurable to suit most laboratory workflows
• Eliminates risk of cross-contamination
• Aligns with established recovery methods
• Designed for use in regulated environments (21 CFR Part 11 and GMP)

Drug recovery for DDU and APSD — four-step workflow

• Load — Test components are placed into dedicated holders within the system
• Dispense — Defined volumes of solvent are delivered to each component and collection surface
• Dissolve — Controlled solvent delivery and rinsing support consistent recovery using established methods
• Collect — Prepared samples are aspirated into HPLC vials, ready for immediate analysis

Additional information
The SRS 100i supports controlled, repeatable execution across runs, analysts and sites and is compatible with Inhalytix®+ for transfer of method and operational parameters to support unified, traceable workflows and downstream data handling.
