GEM Premier 5000 with iQM2

GEM Premier 5000 is a state-of-the-art blood gas analyser for point-of-care and laboratory testing, from heparinised whole blood. The system brings a new level of intelligence to acute care diagnostics: it ensures quality continuously, in real time, before, during and after the analysis of each sample — not just at fixed intervals, as traditional quality control (manual or automatic) does.

The entire testing workflow is built around the single-use “all-in-one” GEM PAK cartridge, which contains all the necessary analytical and quality control components. The operator front-loads a single cartridge, with no maintenance and no refrigeration, and results are available in 45 seconds, including the quality checks. The system is designed to adapt to the specific needs of each department — ICU, neonatology, cardiovascular operating room, emergency — through different menu configurations and testing volumes.

iQM2 — active analytical process control

iQM2 is Werfen’s proprietary system for active control of the analytical process. Unlike classic quality control, it performs continuous checks before, during and after each sample, automatically detecting errors, correcting them and documenting them immediately. As a result, the error detection time drops from hours to minutes, and erroneous results no longer end up being reported.

The new IntraSpect™ technology adds a unique capability: it detects transient, sample-specific errors that traditional QC methods miss — such as micro-clots, micro-bubbles and interferences. During the measurement, IntraSpect collects and analyses 15 sensor readings in 15 seconds, identifying deviations in the signal’s shape and slope that indicate an abnormal sample.

GEM PAK — advanced simplicity at every point of care

The GEM PAK cartridge automates the most labour-intensive processes and includes all testing components: sensors, the CO-Ox optical cell, the lysing solution, the PCS solutions, the tubing, the waste bag and the sampling system. There is a single cartridge to manage in inventory, with no manual troubleshooting and no corrective actions on the part of the operator.

• Zero maintenance — a single single-use, multi-use cartridge is replaced monthly.
• Safety — the components are self-contained, and blood does not enter the analyser, limiting biohazard exposure for the operator and patient.
• No special requirements — easy front loading, room-temperature storage, no refrigeration.
• 31-day use duration (21 days for the 600-test cartridge) — only 12 cartridges per year at a constant volume of up to 450 samples/month.
• 30 GEM PAK configurations available, ideal for both high and low testing volumes.

Connectivity — GEMweb® Plus 500

The GEMweb Plus 500 Custom Connectivity software provides complete control over analysers, operators and data, through a simple and intuitive dashboard, accessible from any analyser, PC or tablet.

• Web access from any browser and real-time remote control, without interrupting testing.
• Automatic operator management, with multi-level authorisation and traceability of users and actions.
• A single database for accessing patient samples and historical results.
• Connection to iQM (GEM Premier 3500/4000) and iQM2 (GEM Premier 5000).
• Open connectivity, including to patient monitors, EHR/ADT systems and non-Werfen analysers.
