PRINCETON APPLIED RESEARCH® (PAR) is a global leader in the manufacture of electrochemical instrumentation including potentiostats and galvanostats for research electrochemistry, applied corrosion, battery and fuel cell research, biomedical research, plating and sensor applications.

Some of the high grade polarographic and ancillary instruements that Princeton Applied Research offers are the following:


	394 Electrochemical Trace Analysis System The Model 394 Electrochemical Trace Analyzer gives you all the advantages and flexibility of computerized data analysis along with Windows compatibility. The analyzer performs routine analyses easily and rapidly. The software features real time plotting, the ability to overlay up to nine files, peak ID, zooming, user drawn baselines and tangents, calibration plots, standard addition and standard curve methodology. Its ease of operation will increase your productivity and performance. The Model 394 provides nine techniques for performing voltammetric and polarographic analysis. These include square wave voltammetry, differential pulse polarography, normal pulse polarography, sampled DC polarography, square wave stripping voltammetry, differential pulse stripping, DC stripping linear sweep voltammetry and cyclic staircase voltammetry.
	QCM922 Quartz Crystal Microbalance The QCM922, an instrument developed for piezoelectric gravimetry in the ng-mg regions, monitors both the resonant frequency and resonant resistance of a Pt or Au coated AT-cut quartz crystal. The resonant frequency changes with the effective surface mass on the crystal, and the resonant resistance changes with the viscosity of the material interfacing with the surface of the quartz crystal. Capable of covering a wide range of applications, the QCM922 was developed primarily for applications where it is used in conjunction with a potentiostat/galvanostat as an Electrochemical Quartz Crystal Microbalance (EQCM)..
	303A Static Mercury Drop Electrode Renewable mercury electrode surface provides higher sensitivity Greater operating convenience than the traditional dropping mercury electrode (DEM) Reduces baseline distortions in DPP and enhances sensitivity Easily converts into an extremely stable HMDE for stripping or squarewave voltammetry Manual or automatic control of purge time, drop size, drop dispensing, and drop dislodgement Analytical calibration plots exhibit excellent day-to-day reproducibility
	616 Rotating Disk Electrode The Princeton Applied Research Model 616 Electrode Rotator is a high precision, low mass rotator that performs well with virtually any potentiostat. When connected to Princeton Applied Research electrochemical instrumentation, it uses control lines to give you remote start/stop and speed control. Using the convenient control panel and input jacks you can operate the model 616 easily for either manual or automated experiments.
	636 Rotating Ring-Disk Electrode The Princeton Applied Research Model 636 Electrode Rotator is a high performance system giving you rapid acceleration and excellent speed control. The Model 636 may be connected to any of the Princeton Applied Research electrochemical instruments. It can be used as a simple rotating disk electrode or as a rotating ring-disk electrode. When configured as a ring-disk rotator, the Model 636 can be paired with the Princeton Applied Research BI-STAT, VSP, or VMP-based multi-potentiostats for ringdisk experiments. This combination can provide a powerful tool for investigations into kinetics, dissolution and mechanisms. Electrical connections to the electrode are made using silver carbon brushes. Consistent, reliable contact is assured by the use of two brushes for each contact to the ring and disk
	FRD100 Frequency Response Detector 0.001 Hz to 120 kHz operation Direct digital demodulation without downconversion 10 µs to 10 ks output time constant Quartz crystal stabilized internal oscillator Synchronous oscillator output for input offset reduction
	273A Power Booster 10A and 20A options Interface available for 273 or 273A Potentiostat Operates in boosted or normal mode Separate interface connects to separate power booster Simple cable connection converts potentiostat from normal to boosted operation
	263A Power Booster 8 A, 10A and 20A options Operates in boosted or normal mode Simple cable connection converts potentiostat from normal to boosted operation Stand-alone or computer-controlled operation Internal interface connects potentiostat to separate power booster Supplied as a complete system or to add-on to an existing 263A Compatible with Electrochemistry PowerSUITE^® software
