Automated BOD Measurement - Mantech MT100 automated pipetting system.

Mantech Automated BOD

  • Software designed for Windows 10 and 11 Pro
  • Incubation tracking
  • LIMS Integration
  • Conforms to ASTM Standard Methods 5210B 23rd Edition, ISO EN 5815, ISO EN 1899-1, -2

Mantech BOS systems automate the 5-day and 7-day BOD and CBOD standard analysis methods using up to five pumps for reagent addition. Automated DO probe calibrations and calibration checks are performed either on the rack or at a separate side position, with automated recalibration and re-reading of previous samples when required.

Management and prioritisation of samples during analysis is simple and the systems feature a customisable user interface to simplify operation whilst results are quickly identified with barcoded labels.

Mantech BOD systems feature auto-populating data entry with YSI meter integration. They perform all calculations with 5 and 7 day tracking incorporating email reminders and the option to add a multi-position autosampler.

The BOD Pro software runs concurrently with all security and operating system updates turned on. Individual account login in credentials mean that administrators can customize permissions for each user’s ability to access and edit software functionality and tag a single analyst to each run reports for enhanced auditing

If integrated directly with the YSI Multi-Lab 4010-W series DO meters the BOD Pro software auto populates dissolved oxygen (DO) readings to the run table. Alternatively manual data entry is available for customers with alternative meters.

Reports and Calculations
Using customisable report templates you can add and rearrange data columns to suit your needs. You can search for past reports by run, name, date, sample ID and/or sample name. Reports can be saved as a CSV or PDF file allowing for easy exporting and/or printing. BOD Pro software performs calculations based on standard analysis methods.

Incubation Tracking
BOD Pro software tracks 5 or 7 day incubation periods. Color-coding creates easy viewing of finals upcoming, due or overdue.

What is the measuring range for dissolved oxygen on BOD Pro analyzers

Mantech BOD Pro analyzers utilize one of two dissolved oxygen probes from YSI for automated dissolved oxygen determination. The measuring ranges of both probes are listed below, along with a link to the complete specification sheets.

YSI FDO 4410 IDS Sensor:

  • Dissolved Oxygen Range: 0 to 20 mg/L
  • Air Saturation Range: 0 to 200%
  • Temperature Measurement Range: 0 to 50°C

YSI ProOBOD Sensor:

  • Dissolved Oxygen Range: 0 to 50 mg/L
  • Air Saturation Range: 0 to 500%
  • Temperature Measurement Range: Ambient 10 to 40°C; Compensation -5 to 50°C
What is the difference between membrane and optical DO probes

Mantech supports both membrane and optical DO probes as both are approved by SM 5210B.

The main benefit of optical over membrane is the maintenance aspect.

  • Membrane probes are much more sensitive to storage conditions, operating practices, and the membranes need to be changed quite often
  • Optical sensor caps last a lot longer and storage is not as critical, though our systems do still store automatically regardless of probe type

Stability Time

  • Stability timing for each measurement is similar, can take a bit longer for optical vs membrane
  • Stability of the measurements over an entire run or between multiple runs is better with the optical

For these reasons, Mantech recommends the optical probe and ~90% of Mantech customers use optical probes. Ultimately, it is your preference and Mantech BOD systems support either probe.

What is the difference between BOD and CBOD

Biochemical oxygen demand (BOD) is a way to assess the amount of oxygen required for aerobic microorganisms to decompose the organic material in a sample of water over a specific time frame. It is the oxygen uptake demand of a source of water. Carbonaceous biochemical oxygen demand (CBOD) is the same method as BOD, but the nitrifying bacteria in the sample are inhibited. Nitrifying bacteria consume nitrogenous materials (compounds with reduced forms of nitrogen) and add to the oxygen demand of the wastewater. Nitrogenous materials are often seen as interference because the purpose of the BOD test is to measure carbonaceous material.

How long does it take to measure initials and finals on a Mantech AM300 series multi-rack system

The length of time to measure initials and finals on a Mantech AM300 series multi-rack system varies depending on the method of sample preparation, sampler size, and probe style.

Is the stirrer turned on manually or automatically

BOD Pro Software™ detects the optimal time to automatically turn on the stirrer while taking DO readings. This feature improves operational efforts for analysts and streamlining your runs.
