Total organic carbon analyzer explained: how it measures water purity and detects organic contamination accurately.
A Mercury Analyzer is a precision analytical instrument used to detect and measure trace levels of mercury in environmental, industrial, food, and laboratory samples. It ensures accurate monitoring for regulatory compliance, safety control, and quality assurance by delivering reliable and repeatable mercury measurements across various sample types.
The Hydra II analyzers incorporate technological improvements to give you exceptional performance, greater analysis throughput and simplified operation. Furthermore, the Hydra II analyzers are built around an innovative, integrated modular design so that the system can be easily reconfigured to perform both Hg reduction or combustion techniques, as your analytical requirements change.
The Hydra IIAA employs the most widely used mercury analysis technique: sample digestion followed by cold vapor atomic absorption (CVAA). This technique’s popularity is in its ability to deliver both sensitivity and selectivity needed to meet or exceed the requirements of many US and European standard methods. With its ng/L detection capability, exceptional stability and powerful over-range protection system the most stringent QCs can be satisfied while its high capacity autosampler assures a long period of unattended operation.
The Hydra IIAA provides fast analysis cycle times; less than 1
minute. Unlike other systems that consume the full sample, it is
able to conduct multiple analyses from the same sample cup in
the same amount of time or less. This approach ensures better
analysis results and samples can be re-analyzed if needed. For
example if intelligent quality control is utilized.
Systems can become contaminated if a sample with an unexpectedly high concentration of mercury is encountered forcing unanticipated shutdown and cleaning. This is easily avoided with the Hydra IIAA’s unique over-range protection by which samples with high mercury concentration are automatically detected BEFORE contamination can occur. Analysis is automatically aborted and the system flushed so the next sample can be analyzed correctly. Unplanned downtime is avoided saving time and money
In EPA Method 245.1 a Laboratory Fortified Blank (LFB) with a mercury concentration >10 times the method detection limit must be run every 20 samples. The chart on the left shows the LFB consistently passes the ±15% accuracy limits (depicted in red).
The Hydra II autosampler is designed for the flexibility needed to take advantage of the system’s fast analysis speed as well as to accommodate the use of a wide variety of low cost sample cups. It has two large reservoirs for recurring QCs, including CCVs and CCBs, with enough capacity for a complete automated run without operator intervention.
The novel gas/liquid separator ensures that samples prone to foaming such as municipal wastewater and industrial effluent do not enter the gas phase and contaminate the system.
A wide variety of commercially available sample cups are supported to achieve maximum productivity and to ensure compatibility with your lab’s digestion vessels
The Hydra II modular design enables one system technique to be reconfigured to another in your lab should your analysis needs change saving money, time and bench space.

A mercury analyzer is an analytical instrument designed to measure mercury concentration with high sensitivity and accuracy. Most modern systems use cold vapour atomic absorption (CVAA) or cold vapour atomic fluorescence (CVAF) technology.
These methods allow detection at parts-per-billion or parts-per-trillion levels. This level of sensitivity is essential for environmental testing, industrial monitoring, and laboratory research.
A Mercury Analyzer is used to detect and quantify mercury at trace levels in solid, liquid, or gaseous samples. In Malaysia, it is commonly applied in environmental monitoring, water and wastewater testing, food safety, petrochemical analysis, and industrial quality control.
Mercury Analyzers are widely used by:
Environmental testing laboratories
Water and wastewater treatment facilities
Oil & gas and petrochemical industries
Food and beverage manufacturers
Universities and research institutions
Government and regulatory agencies
These sectors often require mercury testing to meet safety, compliance, and reporting requirements.
Yes. Mercury testing is often required to comply with guidelines and standards set by Malaysian authorities such as the Department of Environment (DOE), as well as international standards (e.g. USEPA, ISO, ASTM). Accurate mercury analysis supports environmental reporting, audit readiness, and export compliance.
Depending on the model, a Mercury Analyzer can analyse:
Water and wastewater
Soil and sediment
Food and agricultural products
Chemicals and industrial materials
Petroleum products
Some systems allow direct analysis without complex sample preparation.
Most Mercury Analyzers use:
Cold Vapour Atomic Absorption (CVAA) or
Cold Vapour Atomic Fluorescence (CVAF)
These technologies provide high sensitivity, low detection limits, and reliable repeatability for trace mercury analysis.
Industrial-grade Mercury Analyzers can detect mercury at ppb to ppt levels, depending on the technology used. Accuracy and repeatability are suitable for regulatory testing, research, and routine quality control.
Most Mercury Analyzers require:
Standard electrical power (100–240 VAC)
Carrier gas (e.g. nitrogen or argon)
A PC or laptop for instrument control and data processing
Specific requirements vary by model and manufacturer.
Basic laboratory training is usually sufficient. Most suppliers in Malaysia provide:
On-site installation
User training
Operation and maintenance guidance
This ensures safe operation and accurate results from day one.
Routine maintenance typically includes:
Lamp or detector checks
Cleaning sample pathways
Periodic calibration and performance verification
Proper maintenance helps ensure long-term accuracy and instrument reliability.
Key factors include:
Sample type and volume
Required detection limits
Regulatory method compliance
Throughput needs
Budget and after-sales support in Malaysia
Consulting a local technical supplier is strongly recommended to ensure the correct configuration.
