Testing, analysis and research

Your core business (or core activity) is the approach of our approach with regard to testing, analysis and laboratory research. After all, there is no one who knows as much about your activities, your products, your processes and your company as you do.

We from NEDLAB-Xpertlab are happy to combine your knowledge with our knowledge in the field of laboratory tests and analyses or extensive laboratory research to achieve reliable results when you need them. If desired, we not only report dry figures, but we also advise you with regard to these results in combination with your current question.

Products and Materials

The range of raw materials and products that we regularly test and research in our laboratory are very wide, such as:

  • petrochemicals (solvents, aromatic hydrocarbons such as benzene, toluene, ethylbenzene, o-m-p xylene, styrene, organic acids, amines, aldehydes and ketones)
  • fine chemicals
  • cosmetic raw materials and products
  • pharmaceutical raw materials and products
  • beverages (alcoholic and non-alcoholic)
  • fragrances and flavourings
  • vegetable oils and fats
  • food supplements
  • gases (medical oxygen, nitrous oxide, carbon dioxide, nitrogen, high purity gases, food gases)
  • air (compressed air, breathing air, medical air, technical air, ambient air).


The arsenal of tests that we offer is very extensive, depending on raw material or product, here is a small overview:

  • identification
  • purity, assay, content
  • active ingredient, related materials
  • water (KF)
  • acidity, acid number, base number
  • pH
  • contaminants, polutants
  • inhibitor
  • polymers
  • aldehydes and ketones
  • non-volatile compounds
  • color
  • dry matter
  • ash content
  • flash point
  • viscosity dynamic (Brookfield) and kinematic
  • specific gravity, density (pycnometer, areometer, DDM, digital density meter)
  • boiling point, distillation (atmospheric and under reduced pressure), boiling range
  • melting point, freezing point, pour point, melting path
  • refractive index
  • chemical and biological oxygen demand
  • total nitrogen (Kjeldahl)
  • anions: ammonium (NH4+), cyanide (CN-), fluoride (F-), bromide (Br-), iodide (I-), nitrite (NO2-), nitrate (NO3-), sulphite (SO32-), sulphate (SO42-), phosphate (PO43-), acetate (Ac-), sulfide (S2-)
  • total and organic chlorine (Cl), bromine (Br), fluorine (F), iodine (I), sulphur (S), phosphorus (P)
  • alkali and alkaline earth metals: lithium (Li), sodium (Na), potassium (K), magnesium Mg), calcium (Ca), strontium (Sr), barium (Ba)
  • metals: boron (B), aluminum (Al), silicon (Si), scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt/cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), tin (Sn), antimony (Sb), mercury (Hg), lead (Pb), bismuth (Bi) etc. etc.

Analytical techniques

Our professional laboratory offers the following techniques, among others:

  • elemental analyses as ICP-OES, AAS HGA (grafietoven), AA cold vapour (CV = cold vapour); x-ray fluorescence (XRF, EDX)
  • gaschromatografy (GC-FID, GC-TCD, GC-MS)
  • liquid chromatografy (HPLC-UV/vis, HPLC-RI, HPLC-Fluorescentie, HPLC-DAD)
  • ion chromatografy (IC in Combustion-ion chromatografy = CIC)
  • uv-vis spectrometry (fixed wavelength, wavelength scan, time driven scan)
  • Fourier Transform Infrared (FTIR, U-ATR, sandwich, spacer, tablet, gascel 10 cm en 500 cm)
  • various titrimetric techniques (e.g. Karl Fischer)
  • various gravimetric techniques
