Α. Semi-automatic Carbon Analyzer
Automatic Sulfur Analyzer
Q : WHAT IS IT? A : The process flawlessly performed by our Cascade Elec trode Electrophoresis Machine. Q : HOW IS IT ACCOMPLISHED?
/""V.
Oxygen Analyzer
A : Two innovations make it possible: Vertical cascading electrodes provide a uniform horizontal field strength without heat or electrolysis—and—A horizontal trickle feed supplies a uniform vertical hydro-dynamic buffer field. Q : WHAT OTHER ELECTRO-PHORETIC PROCESSES CAN THIS CASCADE ELECTRODE APPARATUS PERFORM? A : Progressive laboratories are utilizing this apparatus for Preparative Strip Chromatography, Star Electrophoresis, Continuous Flow Electrophoresis, Fraction Collecting and Electrochromatography with remarkable accuracy and reproducibility. Q : WELL—WHAT IS ELECTROCHROMATOGRAPHY?
A. Hydrogen Analyzer
A : Simply, the product of vertical and horizontal forces work ing towards perfection. Electrochromatography is the resultant separation of controlled horizontal field strength and controlled vertical hydro-dynamic force. CASCADE ELECTRODE ELECTROPHORESIS available ready for operation with 2000v. 100 millamp, constant-current powersupply, buffer p u m p a n d t a n k .
