Sodium and potassium in food, beverages and water
Israel's red front-of-pack warning labels made sodium a number every food manufacturer must get right. A BWB flame photometer measures Na, K and Ca together in food digests, beverages and water in seconds — and the BWB SUGAR model does it online, 24/7.

Typical samples
Typical samples
Food — sodium and salt
Na for nutrition labelling and salt claims (salt = Na × 2.5), low-sodium and K-enriched products.
Beverages and dairy
Na, K and Ca in juices, soft drinks, sports drinks, milk and infant formula.
Mineral and drinking water
Labelled Na, K and Ca in bottled and tap water.
Desalinated water
Na and K monitoring in desalination product water and remineralisation.
Boiler feed and condensate
Online Na/K to detect sugar or process carry-over before it reaches the boiler.
Sugar, wine and fermentation
K in juices and syrups, Na/K in wine and fermentation media.
Why BWB
Why food and water labs use BWB
- Simultaneous Na, K, Ca. All three from one aspiration; Ba too on the XP.
- Fast QC release. A stable reading in under 15 seconds after warm-up — results on the production line, not tomorrow.
- Simple to run. Step-by-step prompts, auto-read and operator-independent results — suitable for shift operators.
- Online 24/7. The BWB SUGAR takes a continuous sample feed and outputs 4–20 mA and RS232 to SCADA.
- Traceable reports. FP-PC software produces PDF and CSV reports for HACCP and ISO 17025 records.
- Everything in the box — compressor, regulator, standards and labware. Just add propane.

FAQ
Common questions
Can a flame photometer measure sodium in food for labelling?
Yes. After dry ashing or digestion and dilution, sodium is measured directly by flame emission; salt is calculated as Na × 2.5. It is quick, inexpensive and well suited to routine QC.
Is it suitable for water analysis?
Flame emission is a standard technique for Na and K in water (for example ISO 9964-3 and Standard Methods 3500-Na B / 3500-K B), with detection limits of 0.03 ppm Na and 0.02 ppm K.
How does online condensate monitoring work?
The BWB SUGAR collection cup takes a continuous ~5 ml/min sample feed at ambient temperature. Potassium and sodium are measured continuously and sent as a 4–20 mA signal to your SCADA, which can trigger alarms or bypass valves.
