NIC on valmistanut elohopea analysaattoreita jo vuodesta 1978 ja ovat erikoistuneet pelkästään elohopean mittaamiseen. NIC valmistamat elohopea analysaattorit perustuvat fluoresenssi-, termo decompositio-, CVAAS-, CVAFS- menetelmiin. Laitteita on erilaisia laboratorio-, kenttä- sekä on-site mittaustarkoituksiin. Näyteolomuodot voivat olla kaasuja, nesteitä tai kiinteitä näytteitä.
|
NIC:llä on applikaatiotietokanta eri näytetyypeille kuten ruualle, käyttöesineille, biologisille näytteille, ympäristönäytteille, petrokemian näytteille, jätteille, mineraaleille ja monille muille näyteryhmille.

RA-SERIES The RA-Series comprises discrete-direct-purge mercury analyzers, which employ the method of Reducing Vaporization technique for mercury analysis. This technique is also commonly termed as Vapor-Generation or Hydride-Cold-Vapor. In many parts of the analytical world, this technique of Reducing Vaporization – Cold Vapor Atomic Absorption Spectroscopy CVAAS (RA-4500, RA-4300A and RA-5A) and CVAFS (RA-4300FG) is still widely used for mercury measurement. Those are also one of the earliest methods that were adopted by EPA and other regulations in their analytical methodology procedure. Applications: Suitable for a wide variety of post-digested sample solutions, aqueous samples, including drinking water, industrial wastewater, river water, lake water, seawater and rain-runoff Methods: USEPA 245.1 | USEPA 245.2 | USEPA 245.5 | 7470A | 7471B | ASTM D 3223-17 | EN-1483 | APHA 3112 | JIS K0102 | USEPA 1631e | USEPA 245.7 | ISO 17852 | EN-1483 and more |
PE-1000

PE-SERIES
Mercury naturally exists in crude oil with concentrations ranging from parts-per-billion (ppb) to parts-per-million (ppm), depending on its oil field location. Monitoring the concentration of mercury in crude oil before refinery processing is critical. Mercury level in the feeds must be lower than the permittable threshold value to avoid accumulation of mercury within the refinery plant which causes Liquid Metal Embrittlement (LME). The phenomenon of LME compromises the structure of the refinery processes and will cause catastrophic consequences to the plant and jeopardize the safety of the workers. NIC PE-series is designed to perform direct mercury measurement in liquid petroleum-based samples such as crude oil, condensate, naphtha, and the rest of its refined liquid fractions. Applications: Crude Oil | Shale Oil | Condensate | Naphtha | Gasoline | Jet Fuel | Kerosene | Diesel Fuel Methods: UOP-938-20 |

WA-SERIES
WA-Series is a today’s perfect solution for ultra-trace level of mercury analysis for gaseous matrices. WA-Series uses the technique of Dual-Gold Amalgamation, coupling with NIC state-of-the-art detector of CVAAS or CVAFS. Applications: Ambient air | Working environment air | Fuel gas | Natural Gas | Shale Gas | LPG | Other Gaseous Matrices Methods: ASTM D 5954-98 (2014)e1 | ISO 6978-2:2005 | ISO 20552 | JLPGA-S-07 | Ministry Of Environment Japan (MOEJ) Manual method of measuring hazardous air pollutants | UOP 1033-19 | ASTM D 6350-14 | ISO 6978-2:2005 | JLPGA-S-07 | ISO 20552 | USEPA IO-5 |
EMP-3

EMP-Gold+

EMP-SERIES
As in the Minamata Convention Treaty, the main objective is to protect human health and the environment from the adverse effects of mercury. Other than the consumption of food possibly contaminated with mercury, human health can also be affected by mercury exposure in both working and/or living environments with prolonged unaware mercury vapor inhalation. Mercury vapor is colorless and odorless, making it undetectable by human senses at all concentration levels. Once inhaled into the lungs, the mercury vapor is absorbed into the body and bloodstream and is extremely damaging to the human neurological system and our vital organs. Applications: Mostly employed for workplace air measurement for occupational safety. It can be used for direct measurement of gaseous elemental mercury in natural gas, shale gas, and LPG from Tedlar bag, etc. Guidelines: WHO | ACGIH | OSHA | USEPA | NIOSH | ATSDR and more |
SGM-9
|
SGM-SERIES
In the United Nation Environment Programme Global Mercury Assessment Report 2018, artisanal gold mining (ASGM) may be reported as the largest source of mercury emission to the environment, but the combined emissions of stationary combustions coming from coal-fired boilers, cement productions, and non-ferrous metal smelting, easily surpassed those of ASGM. When the mercury from these stationary combustion sources is released into the environment, it methylates with bacteria in the water and bioaccumulates in fishes and shellfish. Ultimately, entering the human food chain. As in the Minamata Convention Treaty, the main objective is to protect human health and the environment from the adverse effects of mercury. Therefore, it is crucial to regulate and monitor these anthropogenic emissions to the atmosphere. SGM-Series is a mercury monitor from NIC which is designed for field use to measure and monitor gaseous mercury in flue gases at the chimney (stack).
Applications: Flue Gas of Coal-Boiler | Waste Incinerator | Sewage Sludge Incinerator | Medical Waste Incinerator | Crematoria and more Methods: JIS K 0222:1997 Procedure 3 |
