IC-ICP-MS method developed to assess carryover effect in chromatography

IC-ICP-MS method developed to test new, reliable way of assessing carryover effect in chromatography. In a recently published paper, M.M. Wolle et al. present an IC-ICP-MS method for the redox speciation analysis of iron based on in-column complexation of Fe2+ and Fe3+. In order to assess the carryover of the...

The new portable 914 combined pH / conductivity meter

The new 914 pH meter from Metrohm, bench top or portable version, a nice modern addition for environmental monitoring. Metrohm has just released their new range of benchtop and portable combined pH/Conductivity meters, the 914 range. The 914 pH/Conductometer is an easy-to-use measuring instrument for routine operation in the laboratory...

New portable 914 combined pH / Conductivity meter for environmental samples

Metrohm has just released its new 914 benchtop and portable combined pH/Conductivity meter. Metrohm’s new 914 pH/Conductometer is a really easy-to-use measuring instrument for routine operation in the laboratory and on the road. pH (or mV) and conductivity (or TDS, salinity) and temperatures can be measured in parallel and output to...

Novel technique for ammonia and amines in ambient air

Ammonia and amines in ambient air: straightforward collection and subsequent analysis by ion chromatography. In a paper recently published in Atmospheric Measurement Techniques, Dawson et. al. present a novel technique for measuring gas-phase ammonia and amines in ambient air. Their technique uses a weak cation exchange resin as a substrate...

Preparation of Soil, Sewage, Sludge and Sediment Samples in the Wastewater Treatment Laboratory

The preparation of a mixture of organic and inorganic samples holds some difficulties: whereas sand, clay and stones can usually be ground to homogeneous samples with suitable laboratory mills, the high energy input can cause samples with organic components such as fat or starch to cake. Waste water treatment laboratories...

Fluorine and Chlorine determination on ores and concentrates

Metrohm CIC complies for ore- and soil analysis. This application work describes the determination fluorine in copper sulphide concentrates using the Metrohm Combustion IC system. This work is also suitable for copper containing ores. Copper concentrate is the first commercial product of the copper production line and is composed of...

Acid sulfate soil analysis, we do it with Metrohm

The Metrohm 888 Titrando in use for acid buffering capacity of acid sulfate soils. Acid buffering capacity of acid sulfate soils can be a lengthy analysis, potentially taking more than 24 hours. Whilst in some instances uneconomical to automate with a sample changer, with the Metrohm 888 Titrando, and controlled...

Conductivity in highly saline solutions – Challenge resolved

Tricky it is indeed to find a suitable cell when challenged by very high conductivity samples such as highly saline solutions. Metrohm’s engineers spent some brain power and time to solve the problem and came up with an optimal solution. They came up with the Metrohm 6.0901.260 cell, with a...

Determination of hexavalent chromium in drinking water according to EPA Method 218.7

Chromium(VI) is movie material. Remember the movie “Erin Brockovich”? With Metrohm you don’t need to worry – Track it down using ion chromatography. The movie “Erin Bronkovitch” is based on a true story and tells the eponymous protagonist`s fight against a U.S. energy corporation that had poisoned the local water...

The Aquatrode — pH stability in low ionic strength samples

Rapid response times and highest precision in poorly buffered solutions, The Aquatrode Plus with inbuilt Pt 1000 temperature probe. pH is a universal measurement in any laboratory, and in most cases a stable pH measurement, given correct maintenance, can be assured. However poorly buffered solutions can prove difficult, leading to...

Continuous monitoring of SO2 in ambient air

This graph shows the daily fluctuations due to human activity and traffic. The Metrohm 920 absorber module in combination with the 930 Compact IC Flex allows us to determine gaseous sulphite in air continuously. Air is sampled through a vacuum pump into the absorption vessel of the 920 Absorber Module...

Determination of Glyphosate in water and soil via Ion Chromatography

Glyphosate, better known under the commercial name as ‘Roundup” is the most widely used herbicide in the world. Glyphosate (N-(Phosphonomethyl)glycine) is a broad spectrum, non-selective herbicide. It is the main component of Roundup (from Monsanto). It causes plant’s death by interfering with the production of certain amino acids. The glyphosate...
