Inline Flow Cells
A wide range of inline flow cells are available with a wide selection of process fitting types/sizes, material types and optical path lengths.
Kemtrak cells have a very small footprint, making them ideal for installation in the tight spaces often found on skids. Additionally, they can be fitted in hazardous areas without the need for the additional electrical installation burden required in such areas.
For quality assurance, all cells are supplied with material certificates as standard. Aside from the material of the cell itself, a range of elastomers is available to suit process conditions and requirements, including options in FDA/USP VI approved materials with certificates. Optical windows are scratch resistant, high clarity sapphire as standard and there are variants for deep UV applications to improve signal strength and instrument range. Fiber optic connections are a standard SMA905 type and compatible both with Kemtrak 007 platform analyzers and many other optically connected instruments. Cells have fittings to firmly seal, hold and protect fiber optic cable connections once attached. All flow cells are pressure tested before shipment.
Single Use Cell System
The Kemtrak Disposable Absorbance Cell System can be used in conjunction with a Kemtrak DCP007 Absorbance Photometer or any other optically connected absorbance instrument to provide real time, online measurement of UV-VIS-NIR absorbance in applications such as chromatographic separation/fractionation/filtration and solvent concentration gradient applications.
The Kemtrak Disposable Cells are available with tube connection sizes from 3/16” to 1”, allowing the same technique and instrument to be used in applications from discovery to full scale production. This ability to “scale-up” the instrument and its measurement technique resolves the problem of having to modify/correlate data already developed at discovery to larger scale instrumentation. This direct transfer allows faster development as there is no need for the repetition of previous work to demonstrate how measured values relate to previous work.
Cells can be delivered with optical path lengths from 10mm to 0.5mm (depending upon connection size), giving a respective full-scale measurement range capability from 2.5 to 50 OD (when used with a DCP007-UV analyzer). With zero dead volume, cells are manufactured from a high-quality medical grade polysulfone material, color coded to allow immediate optical path length identification and are sterilizable either through autoclaving or irradiation. All wetted materials are compliant to USP 87/88 class VI and 21 CFR 177.2600. A zero dead volume in the cells ensures sharp peak detection for fractionation control and filtration applications.
All cells have ready-to-attach hose barb connections. Measurement is performed in a robust, space saving cell dock with quick insertion/release mechanism that precisely positions the cell in the optical light path for reliable measurement performance. The dock includes standard SMA905 optical connections for fiber optic cables. Cables do not need to be disconnected/connected when cells are inserted removed from the dock. When in place in the dock, light passes through the windows and process material in the cell and is returned in another fiber optic cable to connected absorbance instrumentation.
The Kemtrak Disposable Cell System was the winner of the Efficiency Champion Award at Interphex NY in 2019.
