Product Description

 

NATIONALcan recondition gas and liquid cells or repolish crystals of many manufacturers and various sizes. Faster service can be given if cells and crystals are sent directly to our plant accompanied by your purchase order. Your order must include the pathlength required, window material required, and whether or not cells must be calibrated or calibrated and matched. We will also repair or replace luer lock fittings on the front cell plate, if necessary, but at an additional cost.

Liquid Cell Reconditioning: A sealed liquid infrared cell consists of one drilled front window, one undrilled rear window, a front lead gasket, a rear neoprene gasket and a lead or copper spacer which is sandwiched in between the two crystals. This spacer determines the “pathlength” of the cell.

Upon receipt of your cell, NATIONAL decides whether the cell requires complete window replacement, partial window replacement or complete repolished reconditioning. The following conditions determine the type of reconditioning:

Complete replacement reconditioning is when NATIONAL replaces both the drilled and undrilled windows with new windows. See Polished Crystal Price List to determine the cost of new replacement windows.

Partial replacement reconditioning is when NATIONAL replaces one window (whether drilled or undrilled) with a new window and the other window is repolished. See Polished Crystal Price List to determine the cost of the new replacement window and see Repolished Crystal Price List to determine the cost of repolishing.

Full repolished reconditioning is when NATIONAL repolishes both windows. See Repolished Crystal Price List to determine cost of repolishing each window.

All cells are disassembled and reassembled for a fixed cost at almost any pathlength. The standard pathlengths are 0.015mm, 0.025mm, 0.05mm, 0.1mm, 0.2mm, 0.5mm, and 1mm. In the event a pathlength greater than 1mm is required, a nominal cost is added to the price of reconditioning.

NATIONAL recommends calibration of cells or calibration and matching of cells. Cell calibrations are to 4 decimal places (e.g. 0.1124mm). Cells must be calibrated before being matched. NATIONAL’s matched cells are within +/-3% of each other. Cells that are not calibrated can vary as much as 10% from the nominal pathlength. It is recommended that all cells be calibrated. This service is provided at a nominal cost.
