Struggling with Inconsistent GC Results? It Could Be Your Flow

Getting consistent, reliable results in GC often means juggling a lot of moving parts. You carefully optimise columns, detectors, and ovens—but one critical factor still gets overlooked: gas flow verification.

The Hidden Culprit Behind Drift and Variability

Small fluctuations in gas flow can cause significant issues:

• Retention times slowly drifting

• Inconsistent peak shapes

• Troubleshooting sessions you could have avoided

These setbacks are common and expensive, yet often dismissed as "just part of the process." The result? Valuable time lost repeating runs and chasing symptoms instead of root causes.

Meet the 7000 GC Flowmeter

Enter the Ellutia 7000 GC Flowmeter: a compact, handheld solution built precisely for GC applications. Built to help you double check and stay confident in your settings, this tool ensures your carrier gas, column flow, and split lines are set and verified every time.

Here’s what makes it stand out:

• Calibrated for eight common GC gases (including Helium, Hydrogen, Nitrogen, CO₂, Air, Oxygen, Argon, Ar/5% Methane)

• Resolution of 0.1 ml/min, and accuracy of ±0.4 ml/min or 2.5% 

• Flow range: up to 500 ml/min (275 ml/min for CO₂)

• Modes for split flow and linear velocity, lets you quickly calculate values based on your column details

• Pocket-sized, rechargeable, and UKAS-traceable — ideal for daily lab use

Typical Uses in Labs:

• Method development: Confirm your carrier and split flows before every run

• Routine QA/QC: Track performance across multiple systems

• Troubleshooting: Quickly identify the cause of retention shifts

• Training: Show new team members what correct flow settings look like in practice

This isn’t about flashy features or oversized screens. It’s a practical, lab-tested instrument that quietly ensures your GC systems are performing optimally—day in, day out.

Exclusive Offer — Limited Time Only

To help GC labs improve accuracy and reduce rework, the 7000 GC Flowmeter is currently available at a special price of £585(normally £922).
