A method and system is disclosed for streamlined purchase of consumable chromatographic columns and efficient instrument management. Purchase orders for chromatographic columns are entered into based on estimating usage for a fixed period. An initial partial shipment is made of tagged columns as the columns are used. An RFID transmits trigger signals until an order point is reached at which time a new partial shipment is made. This process is repeated until the end of the fixed period. A general control system is in wireless communication with a plurality of apparatuses to ensure prompt and accurate supply of consumables used by the apparatus. As the apparatus uses the consumables, the instrument management system sends indicia from the apparatus to the general control which controls and monitors the number of specific consumables sent to the apparatus.

Apparatuses and methods for wireless monitoring and control of supplies for environmental sampling and chromatographic apparatuses

A liquid chromatographic system includes columns, column mounting fixtures to which the columns are mounted, a detector, a collector, a controller and a plurality of RFIDs. A first RFID communicates with the controller and cooperating RFIDs mounted to other components provide information such as the history of components, parameters and the like. They also receive information from sensors relating to the operation of the liquid chromatograph, store the information and transmit it. Moreover, the RFIDs may substitute for hard wiring in many applications and may enable a central computer to control several liquid chromatographic system.

Sample is applied to a chromatographic column containing shape stabilized packing and the liquid phase is pumped through the shape stabilized packing at a rate of flow greater than the standard rate of flow to obtain at least one of a target resolution and target time of run. Because of the improved resolution provided by the shape stabilized packing at higher rates of flow of solvent, the chromatographer can either obtain better resolution with a standard gradient or shorten the time of the run and reduce the amount of solvent needed by increasing the slope of the gradient.
