Sodium Flame Photometers

Sodium Flame Photometers

UK based SFP Services is a world leading manufacture of sodium flame photometers, specialized test chambers and various other products for air filter and disposable mask testing. Their products are used in over 20 countries by some of the world’s leading manufacturers and numerous global standards are based around and or incorporate the use of sodium flame photometery.

Sodium flame photometers can also be used for filter testing to determine the efficiency of filters in removing sodium aerosols from the air. In this application, the instrument works by first aerosolizing a solution containing sodium ions, which is then passed through the filter being tested. The air that passes through the filter is then analyzed by the sodium flame photometer to determine the concentration of sodium ions remaining in the air after passing through the filter.

The percentage efficiency of the filter can be calculated by comparing the concentration of sodium ions in the air before and after passing through the filter. This method is commonly used in industrial hygiene and environmental monitoring to assess the performance of air filters in removing sodium aerosols, which can be a potential health hazard in certain workplaces or environmental settings.

Like with other applications of sodium flame photometry, proper calibration and standardization of the instrument are essential for obtaining accurate and reliable results in filter testing. Additionally, it is important to carefully control the test conditions, such as the flow rate and concentration of sodium aerosols, to ensure the test accurately reflects real-world conditions.

Overall, sodium flame photometry is a useful technique for filter testing to assess the efficiency of filters in removing sodium aerosols from the air.

Many SFP Services instruments are based on sodium flame technology using a solid sodium chloride aerosol. They have over 50 years of experience in this area. When combined with certain accessories, their photometers can test to ISO 16900 and other popular global standards.
