What is MA-Series?
Highly regarded due to its ease of use, MA-Series comprises two different mercury analyzer models, namely the MA-3000 and MA-3 Solo. Both models utilize the analytical techniques of Direct Thermal Decomposition – Gold Amalgamation – Cold Vapor Atomic Absorption Spectroscopy (CVAAS) to measure total mercury in solid, liquid or gaseous sample matrices.
About Direct Thermal Decomposition
is also known as the Direct Combustion Technique or Direct Mercury Analyzer in the industry.
NIC superiority on knowledge, experiences and know-how on Direct Thermal Decomposition dates back to more than 40 years.
Established in 1978, the first mercury analyzer developed by NIC is based on Direct Thermal Decomposition technique. (Read here for NIC Company history). It was the Model SP-series which was sold and used widely in the Japan scientific community. In the early 90s, with the high demand from the Japanese petrochemical industry for measuring mercury content in Naphtha distillates down to 1 ppb or less, NIC Mercury Analyzer SP-3D was identified and evaluated by UOP. In 1995, SP-3D thermal composition dual-step gold amalgamation mercury analyzer exhibits and prove its performance superiority, officially passing the performance validation and was accredited under UOP 938-95 for the determination of mercury in naphtha. Since then, the UOP 938 method is widely preferred and used by petroleum laboratories to utilize this technique to measure petroleum products directly with high levels of sensitivity, accuracy, precision and data reliability.
Acknowledging the analytical advantage of direct thermal decomposition technique, NIC continues to conduct research and development to improve and optimize the technique to include automation for high-throughput requirements. The MA-Series was subsequently developed and engineered with our latest innovation of Direct Thermal Decomposition from our accumulated experiences of over 40 years and technical superiority know-how since 1978.
It is a product to Choose, Experience and Believe.
Challenges in Mercury Analysis
Benefits of NIC MA-Series
Despite the challenges, direct mercury analysis is one of the most widely accepted alternatives to measure mercury, and NIC MA-Series is built just for that.
REDUCE workflow bottleneck
NO tedious wet chemical sample pre-treatment
HIGHLY accurate and precise results
LOWER operational cost
EASY to use
Operating Principle at A Glance
The desired sample is loaded into the sample boat. The sample boat will be transferred into a sample heating furnace where the sample is heated at a high temperature according to the selected method. The sample will be decomposed, and all forms of mercury compounds will be released into its elemental gaseous form.
The released vapor will pass through the mercury collector tube, where the elemental form of mercury will be trapped onto, forming an amalgam with the coated gold layer. This steps removes interferences
When this thermal decomposition sequence is completed, the mercury collector tube is heated to liberate purified and concentrated pure mercury gas into the measurement cell, mercury is measured by CVAAS at the wavelength of 253.7nm.
