Elemental Analysis

• State of the art instruments for sample preparation via microwave assisted digestion of various sample types and sensitive determination with ICP-OES, ICP-MS, flow injection mercury system
• Determination of organic elemental composition (CHNOS) with an elemental analyser
• Determination of total organic carbon (TOC), dissolved organic carbon (DOC) and total nitrogen (TN) in aqueous solutions

Determination of Chemical Properties

• Broad portfolio of titration methods for organic and inorganic substances
• Determination of chemical numbers, e. g. acid number, saponification number, ester number, hydroxyl number, iodine number, peroxide number
• Determination of colour numbers, e. g. Hazen (APHA), Gardner, Iodine
• Sample separation techniques, e. g. preparative ion-exchanger columns, silica gel column, various solid-liquid and liquid-liquid extraction methods
• Qualitative and quantitative UV/VIS spectroscopy
• Solubility in water and organic solvents, n-octanol-water partition coefficient (logP) by shake flask method
