Dencytee Total Cell Density Sensors
Revolution of Total Cell Density Measurement
Total cell density measurement by the Dencytee sensor is based on optical density, commonly known as the turbidity of a suspension at near-infrared (NIR) wavelengths. All particles and molecules that scatter the NIR light will be detected. This optical density signal can be correlated to the total cell density measured by different offline measurement techniques. Find out more about Hamilton’s Dencytee and Dencytee Arc sensors and their unique measurement modes.
Dencytee Arc
Dencytee Arc sensors enable real-time, in-situ measurement of total cell density using transmittance and reflectance of near-infrared light in low and high cell density applications. Guided in-line/off-line correlation modeling, using the ArcAir software, facilitates the creation of a total biomass sensor. Reduce off-line sampling and increase the reliable optical density measurement range.

Dencytee In Action
From increasing yield to shortening process time, the real power of optical density is in your hands. As shown in the examples below, ask yourself what you could do with continuous process data.
Never Miss an Important Process Event
High resolution, continuous measurement technology enables real-time measurement of the bioprocess, improving process understanding.
Automated Control
Real-time total biomass measurement in-process enables automation and control strategies. Reduce manual intervention by automating process steps such as induction, feeding, or harvest timing.
Correlate to Offline Biomass Measurements
With Dencytee Arc, a built-in correlation model provides a robust link between the in-line optical density signal and commonly used off-line measurements of biomass. Enables real-time, in-situ data of off-line biomass concentrations.

What is special about the Dencytee Arc?
The Dencytee Arc uses two different optical methods: a transmitted light measurement and a reflection measurement. It is effectively a "transflectance" probe. -
Which wavelength is used for TCD measurement?
The Dencytee Arc measures in the near-infrared range (NIR) at 860 nm. At this wavelength, the measurement is unaffected by daylight and changes in the color of the medium. Even strong illumination, such as is required for phototropic organisms, does not influence the measurements. -
Can the OD860 be converted to an OD with a different wavelength?
Although the output of the measured values as OD860 value will not lead to a different growth curve than with OD600, it is often easier to deal with the known quantities and units for reasons of comparability. An OD860 value can be converted to any other measurement or unit, so also to an OD600. The conversion from one unit to another can be made with the correlation.

Dencytee Arc Verification and Service Calibration
Hamilton’s intelligent in-line sensors are designed to record and transmit diagnostic data, including verification information. The verification ensures that a sensor is functioning properly. -
Dencytee Arc Measurement Units
Dencytee Arc monitors in-line optical density (OD) in a wide range of processes. The total biomass sensor detects both live and dead cells, along with any debris or particulates which block light. -
Dencytee Arc Total Cell Density Measurement Principle
Optical density (OD, sometimes called turbidity) is commonly used to estimate the total biomass or concentration of cells within a suspension. Cell concentrations are important to monitor in fermentation processes to detect and correct for process deviations.
