One or more embodiments provide the ability to use multiple path formats in an object oriented system. The machine includes a card reader that can read from cards, user data that corresponds to financial accounts. The affixing strap has a plurality of light admissible end portions and a body portion extended between the light admissible end portions, wherein the light admissible end portions are mounted in the light cavities respectively. The PLL circuit includes a first loop for generating the first control voltage, and a second loop for generating the second control voltage having a phase opposite to the first control voltage. Each track provides a different light pattern. The chromatographic media exhibits a wider pH range and improved pH stability as compared to other silica gel based sorbents, while retaining all other positive aspects attributed to silica gel based sorbents.
