The PC-BOD™  is designed to automate the 5 and 7 Day BOD analysis method approved for use in many countries around the world. Use of the PC-BOD™ will enable laboratories to conform to the following regulatory Norms:

Standard Methods 5210B, 21st edition
Standard Methods 5210B, 20th edition
DIN EN 1899-1
DIN EN 1899-2

With this product release Man-Tech continues its innovative trend of software based, flexible automated solutions for environmental laboratories. The powerful PC-BOD™  software is flexible enough to be set-up to the protocols required by any laboratory, but simple enough to be used on a daily operational level by technicians. The Man-Tech innovation of Autorun Buttons has been fully utilized in the PC-BOD™  software.

PC-BOD™  Software uses the same architecture as PC-Titrate™ reducing the learning time for PC-BOD™  users.

• BOD and CBOD analysis in the same run.
• Automatic addition of inhibitor for CBOD.
• Easily add more samples to batch while running.
• Control up to four pumps for rinsing, dilution water, seed and inhibitor.
• Real time review of finals to be run, with due time and due date listed.
• Ability to re-analyse during and after run completion.
• Ability to reprocess data after BOD/CBOD set has been analysed and closed.
• Automatic exporting of results to a LIMS.
• Real time viewing of flags.
• Autorun buttons for simple operation.
• Auto calibration using the air saturation method.
• Fast dilution pump enabling quick initial batch runs.
• Rinsing between every bottle
• Separate park probe method for storing the BOD probe between runs.
• Follows the 21st edition of Standard Methods allowing seed to be added after 2/3’s volume of dilution water has been added.
• Follows protocols for 5 day and 7 day BOD analysis.
• Other methods are easily incorporated into PC-BOD methods and calculations.

Hardware

The PC-BOD™ automated system uses the NEW Large Man-Tech Autosampler. This attractive, durable autosampler provides a rack capacity of 24x300ml bottles. The rinse pump, liquid level sensor control and BOD probe stirrer control are built into one compact module.

A Man-Tech interface is used with the system. The interface connects to the PC. The dissolved oxygen meter connects to the interface. The autosampler connects direct to the PC.

The rinse pump runs at 260ml/min.The seed and inhibitor pumps run at 12ml/min as they are set to deliver 3-10ml of reagent. If a customer requires less seed, we recommend that the reagent be diluted to deliver larger volumes.

The dilution water pump runs at 620ml/min and is controlled as a volume addition pump and/or controlled by liquid level sensor meeting the requirements of all methods.

The PC-BOD™ is compatible with the YSI Models 52 and 5100 DO meters.
