In order to establish an optimal flow field for the fuel cell working in different pressure conditions, the backpressure
of the test system was modified at two different values (70 kPa and 30 kPa).
conditions exist when a pressure higher than the supply is created in the downstream piping, allowing downstream substances to be pushed into the potable water supply.
AMTAC reduces backpressure
through several design elements.
As such heterogeneous devices usually have different capabilities in terms of cache, battery, and computation, many classical backpressure
based algorithms designed for homogeneous networks cannot perform efficiently in such networks.
A high backpressure
increases the resistance the exhaust gas flow has to overcome before it reaches the exhaust system.
Precise rate control through EMC (electronic mass flow control) technology continually measures hydraulic backpressure
and automatically corrects the application rate on each disc with a variance of less than 1% when comparing desired application to actual application.
They are available in two UHPLC configurations: 2.7 [micro]m superficially porous particles for high-resolution and low backpressure
(stable to 600 bar), and 1.8 [micro]m for highest resolution, stable to 1200 bar.
Perhaps the most common issue that labs encounter when using [beta]-glucuronidase is an increase in HPLC/UHPLC column backpressure
due to incomplete removal of the enzyme prior to injecting the sample onto the column.
Shot volume is injected against backpressure
and metered via a high resolution linear scale.
The problem was that the pumps were constantly breaking down due to excess backpressure
on the mechanical seals, and being obsolete the repairs and maintenance were becoming costly and irritating.
