Ruggedized NIR Spectrometers: Pharmaceuticals/Neutraceuticals/Food/Ag/PAT
Confirming the water content of pharmaceuticals and food during processing is critical for GmP results. The ability to measure water content until recently has been a difficult challenge until now. As a result of developments in the telecom industry, NIR spectrometers offer highly repeatable, cost effective solutions.
Assuring Water Content During Blending and Mixing Results with NIR Spectrometer
Confirming the water content of pharmaceuticals and food during processing is critical for GmP results. The ability to measure water content until recently has been a difficult challenge until now. As a result of developments in the telecom industry, NIR spectrometers offer highly repeatable, cost effective solutions.

It has been well documented that NIR spectroscopy is an excellent method to measure water in powder mixtures. However, absorption curves are different for each given process and are developed for a given manufacturer's process. Once completed, the understanding and control of the blending process has significant benefits and typically pays for the metrology in time savings, waste reduction, faster time to market, reduced maintenance on machinery, and faster process certification.
Better process control and process understanding has intangible benefits as well. With subtle problems sometimes knowing where not to look can have great value.

Blend Uniformity Measurement
The same instrument that can measure your water during process has the ability to assure blend uniformity. In 2004 the FDA published a guidance document for PAT. The real intent of the document is to get manufacturers to fully understand their product completely during the production cycle. This has many benefits, not the least of which is if the FDA has confidence that the manufacturer understands his processes thoroughly, they are more willing to allow changes to the production process. The manufacturer knowing his product better knows where economies can be improved without adversely affecting product.
Benefits of real time in-situ NIR Spectroscopy are:
- Greater control of the process
- Reduced waste
- Improved yield
- Shorter time to market
- Optimized process times
- Better process understanding
- Real-time feedback
- Reduced maintenance
- Minimal operator involvement
- Optimizes equipment utilization
- Improved process documentation
- Reduced manufacturing costs
- Better lot-to-lot uniformity

Testing Solutions for Metals and PFAS in Water
January 22nd 2025When it comes to water analysis, it can be challenging for labs to keep up with ever-changing testing regulations while also executing time-efficient, accurate, and risk-mitigating workflows. To ensure the safety of our water, there are a host of national and international regulators such as the US Environmental Protection Agency (EPA), World Health Organization (WHO), and the European Union (EU) that demand stringent testing methods for drinking water and wastewater. Those methods often call for fast implementation and lengthy processes, as well as high sensitivity and reliable instrumentation. This paper explains how your ICP-MS, ICP-OES, and LC-MS-MS workflows can be optimized for compliance with the latest requirements for water testing set by regulations like US EPA methods 200.8, 6010, 6020, and 537.1, along with ISO 17294-2. It will discuss the challenges faced by regulatory labs to meet requirements and present field-proven tips and tricks for simplified implementation and maximized uptime.
Practical Autodilution for ICP-MS and ICP-OES
January 20th 2025Gain insights into improving efficiency and accuracy in elemental analysis through automated dilution technology. Learn about the key capabilities of the Agilent ADS 2 system and its seamless integration with ICP-MS and ICP-OES workflows.
UV-Vis Spectroscopy: Exporting Your Measurement Out of the Instrument
January 20th 2025Optical fibers in ultraviolet-visible (UV-Vis) spectroscopy can enable measurements outside the traditional sample compartment. This paper details the components needed for fiber optic systems, such as couplers and probes, and reviews the performance of Agilent's Cary series instruments. It is crucial to choose the right fiber optic setup for a specific lab’s needs to ensure accurate and efficient measurements.
