Cartridge port

When a minimum of signal processing is required, analog data can be input through an A/D unit which plugs in directly to the cartridge port of the ST computer (4.) or into a slot of an IBM. 

Most cartridge designs incorporate ports and hardware for connecting environmental controls such as ... 

The Cartridge Concept - has every component part of the sealing system in one unit. They re easier and faster to install and don t require total pump teardown. Most come with additional control ports and rebuild kits. 

While separation takes place in the cartridge housed in the instrument, samples elute from each column through 24 individual exit ports as shown in Figure 6.5. The ports are connected to a bank of 24 flow cells employed for UV absorbance detection. Figure 6.9 depicts one of the individual cells employed. Figure 6.10 shows an overall view of the UV absorbance detection mechanism. 

Figure 10.1 shows a basic online SPE LC/MS/MS system, a column switching system (Kahlich et al. 2006) that includes a six-port switching valve, an injection valve, an SPE cartridge, an analytical column, SPE washing and HPLC pumps, and MS detector. The online process has three steps ... 

Gundersen and Blomhoff (1999) used online dilution with online SPE to measure vitamin A (retinol) and other active retinoids in animal plasma. The intention of online dilution in this application was on optimizing SPE extraction conditions rather than on peak focusing during analytical separation. An SPE cartridge packed with Bondapak C18 materials (37 to 53 jt/M, 300 A, Waters, Milford, Massachusetts) and a reversed-phase analytical column (250 x 2.1 mm inner diameter, Superlex pkb-100, Supelco, Bellefonte, Pennsylvania) were controlled by a six-port switching valve (Rheodyne, Cotati,... 

Product access port connectors (2/cartridge) Push a male/female adapter R90 into the barb hose part of the dialysate hose connector and reinforce with 2 cm of tubing (see Fig. 2). Protect adapter end with a male luer lock cap R96. 

Take out the dialysis cartridge from its packaging, check that all ports are capped, and fix horizontally to a clamp stand. 

Detach the washings reservoir by removing the left dialysate hose connector from the dialysis cartridge, and replace it with a product access port connector Ensure that the end is protected with an R96 cap before opening the bag. 

Tilt the cartridge into the vertical position with the ports on the right side... 

Open the tap at the top access port, and loosen the cap to allow air to pass into the cartridge... 

Remove the port connectors and tubing, and immerse in detergent Carefully dispose of the cartridge with its SP38 adapters still attached in a hazard bag, and autoclave...
