Viable Cell Density Sensors

More Data, More Control, More Possibilities
Continuous on-line, or in-situ, data allows for real-time process control. With off-line data, decisions can only be made at the time of sample analysis, resulting in imprecise timing or missing events entirely. Permittivity is quickly becoming the industry standard for measurement of viable cell volume because of its robust real-time data. It correlates well to off-line cell counting in the crucial exponential phase without the risk of counting errors. When paired with ArcAir Data Modeling software, this correlation can also be made throughout the process. Incyte Arc sensors can be used to increase process quality across many cell lines, process types, and scales.

Incyte Arc
Incyte In Action
From increasing yield to shortening process time, the real power of permittivity is in your hands. As shown in the examples below, ask yourself what you could do with continuous process data.

Process Understanding
Expand your PAT capabilities with permittivity and gain process insights such as cell physiology changes through the use of multi-frequency scan.

Automated Control
Precisely time key process events such as feeding, induction, and harvest for lower production cost, increased yield, and enhanced product quality.

Consistent Quality
Compare permittivity data to ensure batch-to-batch and scale-up reproducibility.

Continuous Process Improvement
Gather on-line viable cell density data every run to enable continuous optimization.

Process Optimization
Real-time data means never missing a key process event. Use this data to develop enhanced process decisions for increased efficiency and prolonged productivity. Alternatively, use ArcAir Data Modeling software for real-time understanding of legacy off-line counts.

Viable Cell Density Soft Sensor
AADM calculates real time viable cell density that correlate to offline measurement and closes all gaps between the measuring points.
The Power of Permittivity
Permittivity measurements are the most reliable method of monitoring Viable Cell Density (VCD). This measurement is immediately affected by changes in Viable Cell Density and can be used to time process-specific actions for maximum yield. Permittivity can also be used to detect changes in cell physiology and is the most immediate method for determining the beginning of the cell death phase.

Continuous Data
Incyte Arc sensors provide a real-time measurement of viable cell density with continuous permittivity data. Off-line samples only provide limited, error-prone data points, so process events may be missed. Real-time permittivity reveals changes in cell physiology, so advanced process control can be automatically triggered for process optimization.
