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 byliquid level sensor meeting the requirements of all methods.
The PC-BOD™ is compatible with the YSI Models 52 and 5100 DO meters.

PC- BOD™ SA
The PC-BOD™ SA (Stand Alone) System is designed for the laboratories that have limited numbers of samples. The benefit is the COMPLETE BOD analysis software and the importance of data integrity and correctness of the results. In addition, there is a simple upgrade path to add an autosampler.
PC-BOD™ SA System
The PC-BOD™ SA System includes the following interface
- A quantity of one 15x300 place rack
Additional options available include:
- YSI Model 52 dissolved oxygen meter
- YSI Model 5905 BOD probe
- Additional 15x300ml racks
- Bar code scanner
- Bar code labels
The various PC-BOD™ SA System Configurations are described below.
Man-Tech does not expect that customer on-site installation will be required. Man-Tech will provide distributors with videos and documentation allowing endusers to install and operate this system without distributors being on-site. We expect some telephone or web support during the installation period and first few runs.
The PC-BOD™ SA offers the additional benefit of being upgradeable by adding the autosampler and required pumps to make an independent automated PC-BOD™ measurement system. This is very important for laboratories investing in the PC-BOD™ SA software solution now with the capability for an upgrade to a fully automated PC-BOD system in the future.
PC-BOD™ SA may be connected to an existing PC-Titrate™, AssayPlus™ or TitraSip™ SA System
The PC-BOD™ SA employs the traditional Man-Tech interface and may be combined with a PC-Titrate™, AssayPlus™ and TitraSip™ SA System. PC-BOD™ and PC-Titrate™ software packages may reside on the same computer and operate independent of each other (they CANNOT be operated simultaneously). This means that a laboratory with a PC-Titrate™ System may purchase the PC-BOD™ SA package for BOD analysis capabilities from the same computer and interface. This is specifically designed for laboratories with limited sample numbers (NOTE: see key technical items below).
There are a few key technical items to note:
- The PC-BOD™ SA is a Stand Alone system. If this is connected to a PC-Titrate with autosampler, the PC-BOD™ SA CANNOT be used with the autosampler.
It resides beside the system and bench space is allocated for it.
- PC-Titrate™ and PC-BOD™ software is installed on the same computer
- While PC-Titrate is operating/analyzing, you CANNOT analyze with PC-BOD™
and vice versa.
- While PC-Titrate™ is operating/analyzing, you CAN in PC-BOD
a. Review and re-process data
b. Set-up timetables, methods and schedules
- PC-BOD™ and PC-Titrate™ software cannot be in operation/analyze mode at the same time.
In summary, both software packages cannot communicate through the interface at the
same time.
An example of a laboratory that will invest in this capability (PC-Titrate™ with PC-BOD™) is a typical inorganic environmental laboratory with a PC-Titrate™ TitraSip™ System for pH, conductivity, alkalinity and turbidity. This laboratory may be running BOD/CBOD’s manually using a rudimentary excel sheet or a simple BOD application commonly offered by some meter companies for data entry/capture. With the inexpensive PC-BOD™ SA add-on to the Man-Tech interface, they now have the complete, powerful PC-BOD™ analysis software. They will immediately notice the peace of mind gained from this package and will appreciate its ease of use.

PC- BOD™SA Software
The PC-BOD™ software will have the look and feel of the PC-Titrate™ software with many functions being the same. There are a number of critical operational differences and these can be learned through Man-Tech videos and/or training sessions.
Main Screen
Main Screen has the innovative Man-Tech Autorun buttons. In addition, the technician/chemist can very quickly view all final runs that are due today including the time they are due at.
Click the Autorun button to begin…
Timetable Entry Screen
In most cases, customers will have their standard BOD templates already created. The PC-BOD™ software has the ability to pre-define sample sets based on customers, sample types, starting protocols, blank-seed-standards, etc. and quickly load/append to build the complete timetable to run at a specific time.
Timetable with Blanks and Seed Samples
Note that BOD and CBOD seeds are mixed together in this timetable. The “Is CBOD?” column lets the software know what type of analysis is defined for the seed, standard or sample (BOD versus CBOD). If the entry is NO, it is a seed for regular BOD samples. If the entry is YES, then the seed is for CBOD samples (samples with nitrification inhibitor added). The YES and NO entries are normally saved as part of the timetable for simple load/append functions. However, if there is a change, it is very easy to edit the entry.
Timetable with Append Checked
To quickly build a timetable, simply check the “Append to Timetable” circle, select the Timetable to add and click “OK”.
Click Start…
Click the “Start” button and the software prompts you for the rack number that the bottles are located in. This is very important for maintaining data and bottle integrity. Once measured, this entire rack will be place in the incubator.
Calibration In Run
The first step in a BOD analysis is the Autocalibration. This requires that a bottle with 1” of water be in bottle position #1 (if defined in this manner) and then follow the on-screen instructions. This is normally done only once during each batch, but can be repeated as often as required during a run.
The OK button reads, “Is bottle with 1” of water in #1 position”. This is a reminder button to remind the technician/chemist about the calibration bottle.
Click “OK” and the autosampler moves the BOD probe to the calibration bottle for a percent method calibration based on air saturation.
Initials Real Time Table
In this table you will notice the first sample is “calib” for the autocalibration. The volume columns are filled in with the actual volumes added as the reagents are added in real time.
Finals
In this screen, the finals have been run, but not “Locked”, they are “unlocked” allowing the chemist to re-measure the sample(s) if there was a flag or other concern. You will notice that the initials have been “Locked” since they were measured 5 days previous and cannot be measured again. Re-measuring initials can be completed on day 1 before they are “Locked”. The new value is saved and the batch results re-calculated. Simply double click on Reset cell for the sample(s) to be re-measured, click start and the system will re-measure only those sample selected. The new DO measurements are saved and used for the BOD/CBOD calculations.
Post Run
In the post run, a completed batch may be loaded and re-analyzed with different calculations (for example Standard Methods versus EN/DIN). The re-calculated results are not saved, but they can be printed for a report.
Post Run with Flags Legend Showing
By clicking on the Flags Legend, a table of flags and their respective meanings appear.
BOD Rule Setup
This allows a specific unique method with rules for the BOD. The BOD and CBOD rules are saved in one method for simple batch analysis and audit trail purposes.
CBOD Rule Setup
A separate CBOD Rule Setup with appropriate rules. The CBOD and BOD rules are saved in one method for simple batch analysis and audit trail purposes.
