To avoid crystallized orthophosphoric acid building up within the pump, the EC1 can be supplied with an automated post-run self-flushing module (DI post acid water-flush delivery). Further protection to the system has been added by coating the unit in Teflon™ to prevent damage from acid splashes.

Water equilibration analysis is again quick, simple, and fully automated. Simply place a vial of water into the heater tray and let the EC1 do the rest.

The precision of both the carbonate and equilibration analysis is greatly improved by the ability to take multiple aliquots from a single sample. As such, the user can look at the average of 2 or more peaks rather than just one.

When combined with a Gilson or Combi Pal auto-samplers, the MultiGas EC1 provides one of the most versatile accurate systems available.

High precision water equilibration and carbonate analysis has always been dependent on the ability to control reaction temperatures with a high degree of accuracy. The MultiGas EC1 achieves this by using dual zone heaters rather than the more common single zone designs. Both zones are controlled by individual 16-bit analogue Newtronic controllers.

The use of multi-zone controllers enables the EC1 to maintain a constant temperature to within 0.1°C within a range of ambient to 200°C.

Carbonate analyses also require a precise and reliable delivery of orthophosphoric acid. It is common to find cheap unreliable rubber-belt driven pumps being used for this purpose. The EC1 avoids this approach, opting instead for a sapphire piston milligat delivery pump. Although more expensive, these pumps provide clean and accurate acid dispensing whilst ensuring standard maintenance is kept to a minimun.
