Industrial Use Cases

Depyrogenation and Sterilization

In the pharmaceutical plants of Ambattur, hot air ovens are used for the depyrogenation of glassware and equipment. This use case involves maintaining temperatures, typically around 250°C, for a specific duration to ensure the complete destruction of bacterial endotoxins. Any deviation in temperature or time can lead to non-sterile products, posing a severe risk to patient safety. Vega Calibration provides the technical soundness required through NABL-accredited validation (IQ/OQ/PQ), ensuring the oven achieves and maintains the required lethality. We ensure your sensing systems are technically robust, protecting high-value industrial batches. By acting as your expert thought partner in process validation and audit-defense reporting, we help you facilitate successful regulatory inspections and provide metrologically sound data.

Moisture Content Analysis (LOD)

Industrial labs in Guindy utilize ovens for LOD tests to determine the moisture content in raw materials and finished products. The critical use case involves the precise regulation of the internal environment to ensure that moisture is removed without degrading the sample itself. Inaccurate temperature regulation during LOD can lead to incorrect moisture readings, compromising the stability and efficacy of pharmaceutical or food products. Vega Calibration provides high-resolution calibration for temperature stability and accuracy, accounting for the unique operational stressors of the lab environment. We ensure your sensors operate with the high-resolution accuracy needed to maintain process stability and consistent results.

Frequently Asked Questions (FAQs)

Q: Why is spatial mapping necessary? Can't I just use a single-point calibration?

A: A single-point calibration only tells you the temperature at the sensor's location. In an oven, air circulation patterns and insulation gaps create temperature gradients. Spatial mapping (9-point or 27-point) is the only way to prove that your entire batch is being heated uniformly, which is a mandatory requirement for pharmaceutical and automotive audits.

Q: How do you handle calibration for Vacuum Ovens where there is no air for convection?

A: Calibration in a vacuum is technically challenging because heat is transferred primarily through conduction via the shelves. We use specialized contact probes or "thermal pads" to ensure accurate measurement of the shelf temperature, which is the actual heating surface for your product.

Q: What is the significance of "Temperature Recovery Time" in an audit?

A: When you open an oven door to load a sample, the temperature drops. Auditors want to know how quickly the oven returns to its setpoint. If the recovery is too slow, your product might not spend enough time at the required temperature, compromising sterilization or curing. We quantify this recovery time as part of our validation.

Q: My oven display shows 150°C, but my internal thermometer shows 148°C. Is this a failure?

A: Not necessarily. Every system has a "Tolerance" or "Acceptance Criteria." As your Quality Manager, we help you define these limits based on your process requirements. We then adjust the oven's offset to align the display with the master standard, ensuring technical accuracy.
