Cartridge arrangements

Figure 7.12 Standard-size disposable cartridges can be connected in series or parallel to handle large flows. This unit consists of nine cartridges arranged in a 3 x 3 array. (From Sartorius product literature)...

Finally, the same authors reported the incorporation of electrokinetic injection into their method (31). Little interference was observed in the separation of MPA, EMPA, IMPA, and PMPA in seven different environmental matrices. Limits of detection were reduced to 1—2 xg/L for water samples, which represented an improvement of two orders of magnitude over their previous work using pressure injection. However, a sample cleanup step was necessary to reduce the conductivity of the sample to be compatible with electrokinetic injection. The samples were passed through three pretreatment cartridges arranged in series to remove sulfate, chloride, and cations, respectively. 

ELAD was developed by Sussman et al. and uses 300-400 g of immortalized C3A human hepatoblastoma cells. Blood is first separated into plasma then passed into hollow fiber cartridges arranged in parallel that house the C3A hepatoblastoma cells, which are fed a separate supply of glucose and oxygen, then passed through a filter to prevent cellular escape and subsequent tumor metastasis, and then returned to the patient (Figure 80.4). Clinical trials have demonstrated that ELAD is safe and reduces progression of hepatic encephalopathy. ELAD has not been shown to improve survival except for a... 

The woven wire mesh type are formed to control the open space between the wires, thereby limiting the maximum size particle that can pass through. The cartridge is installed in cases or small vessels to facilitate quick replacement, or they can be arranged for backwash by use of proper piping connections. The wire wound units have consistent spaces for uniform particle size filtering. 

For more detailed description of particle-velocity measurements, see "Detonation, Particle Velocity in and Its Determination Andreev Belyaev (Ref 44, pp 247-49) describe a method of experimental determination of pressure of detonation, using the arrangement shown in Fig B, Here 1 is charge of an explosive enclosed in a metallic container, and 2 is a metallic (usually aluminum) plate, 1-2mm thick, firmly inserted as a cover at the end of cartridge opposite detonator, 3. On initiation of charge, a shock wave will spread to plate 2 and, when the wave reaches the outer surface of the plate, it will start to move with initial velocity VH (here H is nachaT-naya, which means initial). After determining this velocity experimentally, the...

E) Bullet Impact Test Described by Colver. In the test briefly outlined by Colver(Ref l,p 647), the explosive is packed in cases which are arranged in a longitudinal row at various distances from a rifle. The minimum distance at which an expl detonates is noted as are the number of shots fired, the thickness of the layer penetrated and the velocity of the bullet. The shorter the distance and the larger the number of required shots to cause detonation, the less sensitive is the expi. Loosely-packed expls are usually more sensitive than those packed in cartridge form... 

Fig. 2.46. Basic principle of a venting filter for in situ integrity tests. Arrangement of the sterile venting filters for in-line sterilization and integrity tests (I tests). The integrity tests are carried out following the water intrusion method (WIT). In this figure, WIT is carried out only at the primary filter. The secondary filter is installed as a back-up filter (police filter). 1, Primary filter with a 0.22 pm cartridge 2, secondary filter with a 0.22 pm cartridge the secondary filter can be sterilized independent-...

In this pilot plant the UF pretreatment system is arranged in 2 trains, each housing 3 modules (PAN HF membranes, nominal pore size of 0.02 (im, MWCO 50 000, total effective surface area of 30 m2). Raw seawater (samples from Qingdao Jiaozhou Bay, the Yellow Sea of China) was first passed into a cartridge sand filter and successively feed to UF system, the UF permeate was then pumped to the RO system (spiral-wound composite polyamide) (Figure 12.1).
