Mass Spectrometry Method

One of the official methods used to determine the moisture content of a sample is the Mass Spectrometry (MS) method. It measures the mass-to-charge ratio of ions produced from the sample, providing accurate and reliable results.

How MS Works

A sample is first vaporized and ionized, creating charged ions. These ions are then separated based on their mass-to-charge ratio. The abundance of each ion is detected and analyzed, providing information about the sample's composition.

Advantages of MS

• High accuracy and precision
• Can measure a wide range of moisture contents
• Suitable for various types of samples

Applications

MS is used in various industries, including:

• Pharmaceutical
• Food and beverage
• Environmental

Limitations

While MS offers many advantages, it also has some limitations:

• Can be expensive to purchase and maintain
• Requires specialized training to operate
• Not suitable for all sample types (e.g., highly volatile samples)
