Lumex Instruments applications

The US EPA’s method 30B is designed as a reference method for determination of mercury emissions with stack gases. The method uses sorbent traps to capture total mercury from stack gas. Use of different sorbent traps also enables mercury speciation measurement. Method 30B is widely used for regulatory CEMM verification and for national and international research programs. This technology was also adopted for PRC (HJ 917-2017) and EC (TS 17286:2019).

Introduction: The method is used for the determination of the mass fraction of all primary and secondary nutrients (macronutrients) in fertilizers by capillary electrophoresis. The method allows the determination of such macronutrients as ammonium nitrogen (ammoniacal nitrogen, NH₄-N), nitrate nitrogen (NO₃-N), phosphorus (P or P₂O₅), potassium (K or K₂O) as well as sodium, magnesium, calcium, sulfur, chlorine (chloride), fluorine (fluoride).

Introduction: The method allows determination of water-soluble forms of inorganic (chloride, sulfate, nitrate, fluoride, and phosphates) and organic (acetate, formate, and oxalate) anions in soils, clays, peats, wastewater silts, activated sludges, and bottom sediments by capillary electrophoresis method.

Introduction: The content of water-soluble forms of inorganic cations is one of the substantial characteristics in agrochemical, land reclamation, and sanitary assessments of soils (arable, hayland, pasturable, forest nursery soils). The cation balance should be controlled during ecological soil monitoring for the human activity impact assessment.

Introduction : Analysis of soils, bottom and overburden sediments, rocks and ores for mercury content is one of the most common measurements in environmental pollution monitoring and geochemical exploration. Lumex Instruments proposes a rapid and precise method for direct mercury determination using RA-915 series analyzers based on atomic absorption spectroscopy with Zeeman correction of the background absorption (ZAAS). The thermoscanning option enables the identification of mercury species with varying binding energies to a sample matrix providing additional information in comparison to the total mercury determination.

Introduction: Total petroleum hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil; the main and most specific part of these compounds are non-polar and slightly polar hydrocarbons of the aliphatic, aromatic, and alicyclic structure.

Introduction: The method allows determination of ammonium, lithium, sodium, potassium, magnesium, calcium, strontium and barium cations in samples of natural, potable, and waste water by the capillary electrophoresis method.

Introduction: The method is used for the determination of the mass concentration of inorganic anions: chloride, nitrite, sulfate, nitrate, fluoride, phosphate in samples of drinking, natural, waste waters, and other aqueous matrices by capillary electrophoresis.

INTRODUCTION: This test method is applicable for determination of the dissolved inorganic anions; fluoride, bromide, chloride, nitrite, nitrate, ortho-phosphate, and sulfate in aqueous matrices using capillary ion electrophoresis with indirect UV detection. The method can be applied to drinking water, waste water and ground water.

INTRODUCTION: The method allows determination of bromide and iodide ions in natural, potable (incl. bottled), and mineral water using capillary electrophoresis (CE) method.
