I. Set up for Spectroelectrochemical Synchronized Measurement

The basic configuration and system settings for synchronized spectroelectrochemical measurements using the Model 3325 Bi-Potentiostat (for electrochemical measurements) and the SEC2020 Spectrometer system (for spectrum measurements) is introduced in this section.

The set up for the spectroelectrochemical synchronized measurement consists of three mainly components:
1. Spectrometer (SEC2020 Spectrometer system)
2. Potentiostat (Model3325 Bi-Potentiostat)
3. Spectroelectrochemical reaction cell (SEC-CT Thin Layer Quartz Glass Spectroelectrochemical cell kit (Pt))
Each of the above three components is described below.

1) SEC2020 Spectrometer system

For spectrum measurements, it is a trigger command receiving device.
Different from the usual spectral measurement control, when performing spectroelectrochemical synchronized measurement, the spectrometer needs to be connected to the external trigger control signal input cable (Signal-in cable) to accept the trigger control of the external device. The following lists the components used in the spectrometer system.

Fig. 3-1 SEC2020 Spectrometer system components

Components:
1)  SEC2021 Spectrometer
    1a)  Spectrometer light inlet protection cover
2)  SEC2022 Deuterium halogen light source
    2a)  Light source outlet protection cover
3)  SEC2023 Cuvette holder
4)  Fiber collimator
5)  SMA905 adaptor for light shielding
6)  SEC2024 Platform
7)  Trigger/Light source control cable

2) Model 3325 Bi-Potentiostat

For electrochemical measurements, it is a trigger command output device.
When using the Model 3325 Bi-Potentiostat for spectroelectrochemical synchronized measurement control, the remote cable, which is the signal output cable, is required to connect to the signal input cable of the SEC2020 Spectrometer system. This connection is required for the trigger synchronized measurement controlled for both software, input signal for the spectrometer and output signal for the potentiostat.

RE-1BP Reference electrode (Ag/AgCl)

Since the SEC-C Platinum Wire Gauze Working Electrode (011498) has a platinum wire lead with a diameter of 0.5 mm, it is very fragile and easily bent. Do not clamp the alligator clips of the potentiostat directly onto them. To prevent damage to the electrodes, it is recommended to use the (Cat. No. 011840) IC clip for printed electrodes, for the connection between the electrodes and the potentiostat.
