| Description |
Easy to use
The Apollo 1000 is a single-channel, non-isolated free radical analyzer with extremely quiet analog outputs that allow easy integration into nearly any experimental setup from vessel relaxation studies in a tissue bath to complex in vivo experiments. The pathway of the sensor signal is straightforward. The Apollo 1000 converts the sensor current signal into a voltage at a user selectable gain passing it to an adjustable analog filter block, the signal is then buffered and sent to the output. WPI recommends collection of the signal with our Lab-Trax™ data acquisition interface and Data-Trax software. Pre-configured Data-Trax Setup files for the Apollo 1000 provide optimal settings for data collection and analysis, software adjustments can be made to all acquisition display or analysis options including smoothing and filter adjustments.
Accommodates a wide variety of amperometric sensors
When performing free radical measurement, using amperometry, noise levels are directly related to detection limit. If you are looking at Nitric Oxide from low current output sensors it will be necessary to reduce bandwidth (resulting in lower rise time) to reduce noise. Lower noise reduces the risk that small currents from lower sensitivity sensors could be masked. In species like oxygen or others where output currents are larger and additional noise is not an issue, the Apollo 1000 has the ability to increase the bandwidth of higher current signals for better response.
Poise Voltage Control
The Apollo 1000 has a poise (polarization) voltage range of 0V~ ±2V. In addition, the Apollo 1000 can allow the poise voltage to be driven by an external signal. The split supply (+ and - voltages) together with the external command allow cyclic voltammetry, differential pulse polarography and a host of other electro-chemical techniques not possible with DC poise voltages. When the Apollo 1000 is configured for these types of applications, it is preferable to present the data as an XY plot. Our Data-Trax v2.0 software offers XY plotting and a variety of other mathematical functions. This versatility makes it well suited for analysis and display of electrochemical data.
Potentiometric Input
In addition to its free radical sensor input, the Apollo1000 has a separate potentiometric input. This input has an impedance of 1015 ohms, making it capable of accepting pH electrodes directly without buffer amps. The Data-Trax software incorporates a linear multipoint calibration feature allowing the user to calibrate for linear sensors of any slope or for logarithmic responses such as those from ion selective electrodes. |
