Process Analytical Technology for In-line Bioprocess Analysis
MAVERICK
This easy-to-use process analytical technology device offers in-line bioprocess analysis and control with no complex modeling. Measure multiple critical parameters across media, across processes, across mammalian cell lines, across scales.
All In-line Gain, No Modeling Pain
MAVERICK is powered by Raman spectroscopy and a purpose-built de novo model. The de novo model is explicitly built on media chemistries and device physics, not on empirical data. It automatically interprets the spectra and quantifies process parameters enabling simultaneous measurements of glucose, lactate, and total biomass. This is achieved without the costs, complexities, and risks associated with conventional Process Analytical Technology (PAT) methods. There is no need to grapple with complex empirical models, reagents, or unreliable auto-sampling systems to implement in-line bioprocess analysis.
How the De Novo Model Works
The MAVERICK measurements are based on a de novo model. This model was developed from first principles without empirical observation/calibration in bioprocesses with any particular media. The de novo model considers both static and dynamic parameters measured during the actual bioprocess runs. One of the static parameters is a formulary which includes the spectral characteristics of many chemical components in media. These include glucose, lactate, and other cell culture media components detectable by Raman. The dynamic parameters include adapting to changes in environmental factors such as ambient light, temperature, and turbidity, including cell based fluorescence. It also accounts for the characteristics of each unique device from an optical, electronic, and measurement error model perspective.

Process Analytical Technology (PAT) Made Easy
While in-line process analytical technology (PAT) offers many benefits, adoption has been hindered by technical challenges, integration issues, and significant implementation costs.
MAVERICK addresses all these issues, ushering in an era of accessible, continuous monitoring of multiple parameters. With MAVERICK, your team can stay at the forefront of Bioprocessing 4.0 and fully harness the advantages of real-time in-line bioprocess analysis (bioreactor monitoring) and control. Intuitive setup and user-friendly interface means there is no training barrier to overcome.
MAVERICK – Easy to Learn, Easy to Use
MAVERICK is intuitively designed for ease of use, requiring no prior experience with Raman spectroscopy or chemometric modeling. It features a user-friendly hub with a high-resolution color touchscreen, CFR 21 Part 11 compliant software, and an intuitive interface that simplifies in-line bioprocess analysis. With MAVERICK, mastering bioprocess monitoring is straightforward and efficient.
Instant Raman, Ready in Minutes
MAVERICK offers all the advantages of Raman-based process analytical technology (PAT) without the cost and complexities associated with developing “black box” empirical calibration models, required by conventional process spectroscopy-based methods. While it can take months and a dedicated team of experts to build and validate a robust empirical calibration model—MAVERICK only takes a simple two-point probe calibration to begin monitoring multiple key process parameters in most types of bioreactors. Just take it out of the box, and you’re already halfway through the setup process.

Frequently Asked Questions
What applications can MAVERICK be used for?
MAVERICK is intended for bioprocessing applications in process development and biopharmaceutical manufacturing, enabling cell culture automation in biologic production for CHO or HEK293 mammalian cell line and media. For example, MAVERICK can help optimize viral vector titer in lentiviral vector production, AAV production, and other viral vector manufacturing applications.
Which cell lines and cell culture media does MAVERICK work with?
MAVERICK works with CHO and HEK293 cell lines and media.
Which bioreactors are compatible with MAVERICK?
MAVERICK autoclavable immersion probe is 220 mm long with 12 mm outside diameter, making it compatible with most 250 mL to 10L bioreactors. The PG 13.5 compression fitting interfaces with the standard bioreactor sensor ports and enables adjustment of the immersion depth (minimum 40 mm immersion depth is required).
I simultaneously operate more than one bioreactor. Can I multiplex MAVERICK to multiple vessels?
Yes. Each MAVERICK Hub connects and controls up to six Measurement Modules, supporting up to six individually or jointly operated bioreactors. Unlike other process Raman spectroscopy analyzers that employ optical switches or multi-channel design, MAVERICK preserves operational redundancy in multi-bioreactor applications.
How is MAVERICK calibrated?
The probe is calibrated using the two standards in the Calibration Kit. Calibration is performed prior to autoclaving the probe, before each bioreactor run. Each probe has a built-in memory chip that stores its calibration coefficients and verifies that the correct probe was re-attached post-sterilization.
How does the feedback control loop automate substrate feeding based on in-line measurements?
On-board analog/digital controller offers optional direct control of feed pumps. Alternatively, the measured values can be sent to an existing bioreactor controller, SCADA, or data acquisition system via Analog outputs or OPC UA protocol.
How are probes sterilized?
Probe barrels are autoclavable or steam sterilizable and should be replaced after 10 autoclave cycles to ensure the probe maintains its integrity.
Why doesn’t MAVERICK require the development of multivariate models to correlate Raman spectra to cell culture process parameters?
Normally, interpreting the spectrum from Raman spectroscopy requires the development of empirical multivariate calibration models (chemometric modeling) specific to analytes of interest. This requires multiple bioreactor runs to acquire real-time spectral data, manually collect numerous samples from the bioreactors for at-line/off-line analysis, and then utilize statistical analysis to correlate the Raman spectra to the at-line/off-line measurements. Naturally, this process is very time consuming, expensive, and complicated, making Raman-based bioprocess monitoring inaccessible to most biopharma labs.
MAVERICK purpose-built De Novo Model does not need to be trained on empirical process data. The model quantifies analyte concentration by accurately inferring peaks, associated with the analytes of interest based on a priori knowledge and the baseline from water, other mixture components, and instrumentation in the spectra.
Is MAVERICK available outside the United States, and do you provide global technical support?
