The first method imposes too many limitations on the system to make it viable in practice, while low-flow high pressure liquid chromatography is still being developed and has only been reported for the separation of mixtures of pure compounds.

Catalytic activity was studied in laboratory and bench-scale reactor systems. Laboratory catalytic tests (n-hexane conversion) were carried out in a through-flow reactor under the following conditions T=200-450 °C LHSV=7 h. Bench-scale tests were run in a continuous -flow high-pressure microreactor unit, using diesel oil as a feedstock. Catalysts were reduced and then sulfided at 330 °C for 5 h. The process was studied at T=300-330 °C, LHSV=3 h p=3.5 MPa and H2 CH=500 Nm /m. The criterion for catalyst activity assessment was the freezing point (-20 °C) the measurements were done for the stabilized products.

The number of particles applied for MAA scintigraphy is typically much less (approximately 150,000 particles) hence, the application does not result in hemodynamically relevant effects. Slow application of MAA might, therefore, lead to a predominant flow of MAA into large vessels with high blood flow. High-pressure application of MAA could, on the other hand, result in undesirable extrahepatic distribution due to retrograde flow. 

A low liquid flow rate is essential for lower oxide and other polyatomic interference formation, so a low-flow, high-pressure nebulizer made of PP or PFA is necessary. Self-aspiration with an Elemental Scientiflc PFA-ST, one piece nebulizer with 0.25-mm internal diameter (i.d.) (approximately 100 pL/min) uptake tube and probe has been used for this purpose to eliminate liquid surging in the plasma that results from peristaltic pumping. An equivalent low-flow nebulizer may be used. 

The AP 600 turbine consists of a double-flow, high-pressure cylinder and two double flow, low pressure cylinders that exhaust to individual condensers. It is a four flow tandom -compound, 1800 rpm machine. The turbine generator is intended for base load operation and also has load follow capability.

The CANDU 3 turbine conasts of one double flow high pressure and two double flow low pressure turbines, operating at 1800 rpm. 

The turbine K-160-4.2 consists of a single - flow high pressure cylinder, and double-flow low pressure cylinder that exhausts to the condenser. The two moisture separator/ reheaters are integrated in the main turbine system. The reactor plant is combined with one turbine generator designed for base load and load-following operation. 

The Steam turbine is a tandem compound unit, generally consisting of a double-flow, high-pressure turbine and three double-flow, low-pressure turbines, which exhaust to a high vacuum condenser for maximum thermal efficiency. The condenser may be cooled by sea, lake, or river water, or by use of atmospheric cooling towers.
