The Ektachem story starts in 1970 at the Eastman Kodak Co. in Rochester, NY. For some time, Eastman Organic Chemicals had supplied reagents to the clinical laboratory. Al Baitsholts, product manager for a thin-layer chromatographic system of impressive analyte sensitivity, became convinced that some kind of thin-layer format might form the basis for a new approach to routine clinical chemistry ...

Extended clinical trial and evaluation of glucose determination with the Eastman Kodak Ektachem GLU/BUN Analyzer.

We followed the "abbreviated precision protocol" of the National Committee for Clinical Laboratory Standards for the evaluation of precision, accuracy, and carryover in analyses for glucose with the "Ektachem." We analyzed 760 clinical samples by this technique, by the FDA Proposed Class Standard glucose reference method, and with the Beckman System I GLU/BUN Analyzer. Precision and accuracy we...

The Eastman Kodak Multiple-Stylus Electronic Printer

THE Eastman Kodak multiple-stylus electronic printer prints, at high speed, outputs from electronic computers, insurance premium notices, utility bills, addresses on magazine labels, addresses on cards and envelopes, and so forth. High-speed printed communication is also a field for this printer, as it can be operated by remote control, without synchronization. This nonphotographic electromecha...

Clinical evaluation of Eastman Kodak's Ektachem 400 Analyzer.

We evaluated the performance of the Kodak Ektachem 400 Analyzer in a 16-week clinical trial. We assessed four potentiometric tests and nine colorimetric tests for precision and correlation with results obtained some other commonly used instruments (Technicon SMA II and C800 System, Du Pont aca II, and Baker CentrifiChem). The comparison was favorable for all tests except albumin, sodium, and ca...
