Blood processing

SPME-IR has been applied to VOCs in soil samples [547], Industrial applications to in-process streams can well be envisaged. SPME has not yet extensively been explored for polymers, but the determination of residual volatiles, semi-volatiles and degradation products in polymers has been reported [548]. It is equally well possible to use SPME for plasticiser analysis in various matrices (water, milk, blood, processed food, etc.).

The American Red Cross also had significant issues raised during an inspection in 2002 of its blood processing computer systems. 

The computer systems used within each of these levels tend to have common characteristics that will influence their validation. For instance, measurement and control systems are generally configurable Commercial Off-The-Shelf (COTS) instruments. Examples include control instrumentation, analytical instrumentation, and medical devices including blood processing systems.

Effective from 1997, such registration is mandatory for systems used in blood processing other software groups, including LIMS, are likely to be included in the mandatory classification over the next three to five years. W validation performed by a vendor is suspected because of a lack of a QA norm in the industry a validation signed by a credible outside expert has much more weight.

For methods that analyze serum or plasma, it is useful to process whole blood samples by centrifugation, followed by separation of the plasma/serum from the red blood cell (RBC) pellet. The plasma or serum components can then be frozen ( 70°C or dry ice preferred) and stored or shipped on dry ice. As on-site blood processing may not be convenient, whole blood samples that are not processed should be stored immediately at 4°C. Packed RBCs may be stored at 4°C or frozen depending on the properties of the analyte and the needs of the analytical method to be performed. 

The dialysis processes (especially electrodialysis) are used for the selective extraction of ions from solution in w ater and/or their concentration in one liquid stream. The most important application of dialysis (blood processing for kidney action support) is not replicated in the chemicals sector, but electrodialysis, using ion exchange membranes, is finding increasing usage. ... 

Several classes of polymeric materials are found to perform adequately for blood processing, including cellulose and cellulose esters, polyamides, polysulfone, and some acrylic and polycarbonate copolymers. However, commercial cellulose, used for the first membranes in the late 1940 s, remains the principal material in which hemodialysis membranes are made. Membranes are obtained by casting or spinning a dope mixture of cellulose dissolved in cuprammonium solution or by deacetylating cellulose acetate hollow fibers [121]. However, polycarbonate-polyether (PC-PE) block copolymers, in which the ratio between hydrophobic PC and hydrophilic PE blocks can be varied to modulate the mechanical properties as well as the diffusivity and permeability of the membrane, compete with cellulose in the hemodialysis market.

Tsai and Haynes [52] by contrast claim the use of cloud point antifoams for cardiotomy and general extracorporeal blood processing. These compounds are exemplified by polyoxyethylene-polyoxypropylene block copolymers of formula OH.EO PO ,EO H with cloud points preferably < 20°C. They are non-toxic and compatible with blood. At temperatures > 20°C in aqueous media, these polymers...

The methods of preparation and isolation as well as the bioassay for LM activity used by the various groups were not identical. Therefore the equivalence of the various peptides is uncertain. Lipovetsky (1964) concluded that Rudman s material was similar to Selfter s and reported LM acHvity for human blood processed by the procedure of Seifter and Baeder and assayed by the method of Rudman. 

Other Uquid separation systems using membranes include dialysis and electrodialysis, where the driving force is now a concentration difference between the two sides of the membrane. The main use for dialysis is in blood processing, as a kidney replacement or booster, but both processes are also being used industrially, electrodialysis especially in desalination.
