Cell Density Sensors
The Power of In-Line Cell Density Measurement
On-line, or in-situ, measurement is the pinnacle of process monitoring and necessary for true process control as evidenced with control of pH and dissolved oxygen, common for most biological processes. In fact, many parameters can be monitored but those directly related to cell physiology are typically time consuming off-line measurements that provide only a reactionary window into the past. Incyte Arc and Dencytee sensors provide a means for directly measuring viable cell density and total cell density in real-time, meeting the increasing need for PAT in the biopharmaceutical industry.

How Does Cell Density Measurement Work?
Many parameters like pH and dissolved oxygen can be monitored in-line but those directly related to cell physiology are typically time consuming offline measurements that require many manual steps. Total and Viable Cell Density measurement is now possible in-line with a new breed of sensors. Learn more about saving time and effort and increasing productivity and process understanding with in-line cell density sensors in the video below.

How does Incyte measure viable cell density?
Incyte is a capacitance-based sensor responsive only to living cells. -
What is the effect of agitation variations on the Incyte measurement?
The agitation can influence the size of air bubbles. This number and size of air bubbles can affect the Cell Density measurement. -
Can the electric field of Incyte damage/harm the cells?
No. The frequency of the electric field applied by the system is within 300 kHz and 10 MHz. These frequencies do not damage the cells.
