HOW TO CHOOSE A WATER ACTIVITY METER? When it comes to water activity instrumentation, there are lot of choices out there. The one that is best for you will depend on several factors. If you just want a number, there are cheap options that will give a number, but come with no support. If you…
1. Executive Summary By 2050, the world’s energy consumption is expected to increase by nearly 50%, posing a significant challenge for current battery technologies to grow sustainably and cost-effectively.1 Although lithium-ion systems still dominate the market, emerging chemistries such as redox flow, aluminum-air, and aqueous (water-based) batteries aim to address cost, safety, and environmental concerns.2-4…
Water activity is an important quality control parameter in many industries, especially when product safety, microbial stability and shelf life need to be evaluated. For QC teams, the key point is simple: a water activity result is only useful if it is measured with a suitable method, a reliable instrument and proper calibration standards. Why…
There can be an abundance of confusion with water activity instruments concerning test time. Some instruments claim a 5-minute test time, while others offer fast or quick modes. Water activity test time is primarily driven by the physical and chemical characteristics of the sample, not by the instrument itself. Since water activity is an equilibrium…
In critical quality applications, water activity measurement is more than a routine laboratory parameter. It can influence decisions on product release, shelf life, chemical stability, microbial safety, packaging, and quality assurance. For this reason, accuracy, repeatability, and long-term measurement reliability are essential. Novasina is known for highly reliable and precise water activity measurement technology. The…
This calculator helps you compare the total cost of ownership of a Novasina water activity system with another water activity instrument based on a different sensor technology. The calculation includes the main cost drivers over the selected evaluation period, such as instrument investment, software costs, calibration materials, recurring service costs, and operational effort. This makes…
This practical decision calculator helps you estimate whether investing in an in-house water activity instrument is financially worthwhile compared with routine testing at an external contract laboratory. By entering a few key assumptions, such as instrument price, expected sample volume, external laboratory cost per sample, internal working time, and annual service costs, you can quickly…
Since water activity testing is critical to ensure the quality and safety of manufactured products, it is common to find water activity instruments in most quality assurance laboratories. As with any laboratory test method, good laboratory practices require routine verification assessments for water activity to make sure the instrumentation is working properly. This can be…
The shelf life of a product is the period during which it remains acceptable and desirable to consumers. It defines how far the product can be distributed, how it should be stored, and which best-before date can be assigned. If the actual shelf life does not meet expectations, the result can be customer complaints, product…
The international coffee market is valued at $102 billion. It includes everything from freeze dried instant coffee to specialty blends carefully sourced from specific growing locations. Not surprisingly, the highest quality coffee comes at the highest price along with the highest quality expectations. Coffee beans are harvested as a coffee cherry that is then processed…
