SulfiteCheck™ Sulfite Detector
The ChemSee SulfiteCheck™ sulfite detector is a rapid colorimetric test for screening food and beverages for sulfites. The compact detector uses separate sample and quality-assurance areas to provide an easy-to-interpret visual result without an electronic reader.
5 ppm Sensitivity
SulfiteCheck™ is designed to detect sulfites at concentrations as low as approximately 5 parts per million (ppm).
Under 3 Minutes
The detector develops its visual response in approximately 3 minutes after the prepared sample is applied.
Quality Assurance
A separate quality-assurance area develops a blue response to confirm that the applicable detector chemistry is functioning during the test.

How SulfiteCheck™ Works
Prepare the sample when necessary, apply liquid to both sides of the detector and interpret the color response after approximately three minutes.
Prepare Sample
- Liquids: Use the sample as-is.
- Solid foods: Mince or cut into small pieces.
- Mix the solid sample with approximately an equal volume of water.
- Mix thoroughly before testing the liquid portion.
Apply Sample
- Place a small amount of liquid sample on the marked openings.
- Apply sample to both sides of the SulfiteCheck™ detector.
- Make sure the applicable test areas are adequately wetted.
Wait & Read
- Allow approximately 3 minutes for the test to develop.
- The quality-assurance side should develop a blue response.
- A white response on the sample side indicates sulfites are present.
- If blue develops throughout, sulfites are not detected under the conditions of the test.
Interpreting SulfiteCheck™ Results
Use both the sample response and the built-in quality-assurance response when interpreting a SulfiteCheck™ test.
No Sulfites Detected
When the quality-assurance chemistry responds properly and blue color develops throughout the applicable test areas, sulfites are not detected under the conditions of the test.
Sulfites Detected
A positive sulfite response is indicated when the quality-assurance side develops its expected blue response while the sample side remains or becomes white.
Important: Always interpret the test using the instructions supplied with SulfiteCheck™. Sample color, composition, preparation and other matrix effects may influence a visual colorimetric result.

Common Sulfite Screening Applications
Sulfites are used in many foods and beverages as preservatives, antioxidants or processing aids. SulfiteCheck™ can be used to screen suitable samples from a range of common applications.
Wine, Beer & Juices
- Wine
- Beer
- Cider
- Fruit juices
- Bottled lemon or lime juice
Fruits & Vegetables
- Dried apricots
- Dried pineapple
- Dried mango
- Sun-dried tomatoes
- Other dried or preserved produce
Other Food Samples
- Shrimp and shellfish
- Condiments and sauces
- Pickled foods
- Prepared or processed foods
- Other suitable liquid or extracted samples
Screening result: SulfiteCheck™ is designed as a rapid colorimetric screening test for sulfites in suitable food and beverage samples. It does not provide an exact numerical sulfite concentration and is not a medical test for sulfite sensitivity or allergy.
For customers who prefer professional analysis rather than performing and interpreting a direct test, ChemSee also offers mail-in sample testing.
