The CELL Connector Cable for the Ametek/EG&G Princeton Applied Research 263A Potentiostat/Galvanostat establishes a low-noise interface between the instrument and electrochemical cells. Engineered for high-impedance measurements, this cable delivers the input bias current and differential electrometer performance required for picoampere-level detection and fast transient capture.
– Technical Specifications
• Input Bias Current: Less than 20 pA typical
• Differential Electrometer Input Impedance: Greater than 10¹² Ω in parallel with 20 pF
• Bandwidth (Differential Electrometer): –3 dB at greater than 4 MHz
• Connector Type: CELL connector with grooved sleeve for repeatable insertion and alignment
– Key Features
• Minimizes noise and drift in potentiostatic and galvanostatic measurements
• Supports acquisition at 30 µs timebase intervals
• Enables current measurements across 7 decades from 100 mA to 100 nA
• Facilitates potential steps as small as 250 µV
• Compatible with 14-bit bias DAC and 16-bit modulation DAC architecture
– Instrument Performance
When paired with the 263A, the system achieves:
• Minimum current resolution of 2 pA
• DC accuracy at monitor of 0.4% full scale (10–100 µA range)
• DC accuracy at monitor of 0.5% full scale ±5 nA (100 nA and 1 µA ranges)
• Power amplifier compliance voltage of ±20 V
• Power amplifier slew rate exceeding 1 V/ms (no load)
• Power amplifier rise time under 1 ms (no load)
– Compatibility & Integration
Designed exclusively for the Ametek/EG&G Princeton Applied Research Model 263A Potentiostat/Galvanostat, this cable connects directly to the CELL connector on the instrument front panel. The grooved sleeve design ensures secure mating and alignment for consistent contact quality across measurement sessions.
