MFC™: Mass Flow Control Accessory

Electronic control of split and desorb flows is offered by 1 or 2 optional mass flow controllers (MFC) which are integrated into UNITY 2 as shown.

These provide versatile electronic control of both split and desorption flows, featuring flexible split flow rate selection combined with precise control at low flows.

The UNITY 2 MFC modules also facilitate flow rate recall during an automated sequence with multiple TD methods.

Standard UNITY 2 systems feature the full range of split options (splitless, single split and double split), but with manually controlled flow rates.

Two options are offered:

2 - 100 ml/min
5 – 200 m/min

For added versatility, series 2 ULTRA 50:50 systems also offer the option of 1 or 2 integrated MFC’s for special applications.
