GHM-01 Heavy Metal Detector
The ChemSee GHM-01 heavy metal detector is a rapid colorimetric test for screening water, beverages, prepared food samples and other suitable liquids for common heavy metals. The test develops a visible color response that is compared with the supplied reference chart.
8 Common Metals
The GHM-01 screens for lead, mercury, cadmium, thallium, cobalt, iron, nickel and zinc using a visual color-reference system.
Color-Based Identification
A color develops in the test vial after reaction with the sample. Compare the response with the supplied chart to help identify the responsive metal.
Flexible Sample Testing
Liquid samples may be tested directly. Solid foods are first mixed with water so the liquid portion can be introduced into the detection vial.

How the GHM-01 Works
Prepare the sample if needed, activate the detector, add the sample and compare the developed color with the supplied heavy-metal reference chart.
Prepare Sample
- Liquids: Use the sample as-is.
- Solid foods: Chop into small pieces and mix with approximately an equal portion of water.
- Mix thoroughly for about 3 minutes.
Activate & Add Sample
- Remove the sealed vial and test paper from the packaging.
- Place the test paper inside the vial and reseal it tightly.
- Shake for approximately 5 seconds and allow the liquid to settle.
- Open the vial and add sample to the marked fill line.
React & Read
- Shake vigorously for approximately 15 seconds.
- Allow the liquid to separate for approximately 60 seconds.
- Observe the color formed in the upper liquid phase.
- Compare the result with the supplied reference chart.
GHM-01 Detection & Kit Details
The GHM-01 combines multi-metal colorimetric screening with a visual reference system for qualitative identification of common heavy-metal responses.

Identify the Color Response
- Observe the color in the upper liquid phase after separation.
- Compare the response with the supplied GHM-01 color reference.
- Identify the metal response that most closely matches the developed color.
- No electronic reader is required.

Screening result: The GHM-01 provides qualitative colorimetric screening and identification. It does not provide a numerical concentration for the detected metal. Samples containing multiple responsive metals or complex matrices may also produce results that are more difficult to interpret.
When exact concentrations, regulatory determinations or confirmatory analysis are required, appropriate laboratory testing should be used.
Need Heavy Metals + Arsenic?
ChemSee also offers bundled THM kits that combine the GHM-01 with an arsenic detector. Choose elevated-level or trace-level arsenic screening based on your application.
Heavy Metals + Elevated Arsenic
Combines the GHM-01 with the AJ-05 for applications involving comparatively elevated arsenic concentrations.
AJ-05 approximate threshold: 500 ppb
Heavy Metals + Trace Arsenic
Combines the GHM-01 with the AJ-LOW-01 for applications where lower arsenic concentrations are important.
AJ-LOW approximate range: 1–100 ppb
