Consumers want to eat and drink delicious dairy products with confidence. There should be no doubt about this. Food safety is therefore always a priority for dairy producers and the entire chain. Many analyses are carried out to safeguard food safety, and they are closely monitored by the government.


Pathogens such as Listeria, Salmonella, Cronobacter and E-coli should not be present in dairy products. We conduct many microbiological analyses every day to prevent possible contamination from the production environment to dairy products. The following advanced techniques are available within our microbiology department: standard plate methods, PCR, Vidas Up, Maldi-Tof and pathogen typing.

Contaminants and residues

Our laboratory has a wide range of recognised analyses available to detect contaminants and residues in dairy products at very low levels.


Our instrumental chemistry department is specialised in research into antibiotic residues/growth-inhibiting substances with the use of LC-MS. More than 80 different antibiotics can be identified.

Other contaminants

Knowledge and methods are available to detect all kinds of unwanted substances, such as radioactive materials, pesticides, dioxins and PCBs, PAHs, melamine and anthelmintics.

Aflatoxin M1

Analysis and confirmation of the presence of Aflatoxin M1 in milk is conducted for customers around the world. Qlip is the leading laboratory for confirmation of Aflatoxin M1, using the reference method by means of HPLC technology.

Heavy metals

Cadmium, mercury, lead, arsenic and other heavy metals are measured by using ICP-MS technology. Ask about the possibilities.

Reliable test results

Applied analysis methods are usually conducted according to recognised ISO or NEN standards. Qlip is accredited by the Dutch Accreditation Council and has the NEN-EN-ISO-17025 accreditation, registered under number L099. Many activities are therefore carried out under accreditation under the scope Dairy. The most recent list of accredited activities can be found on the website of the Dutch Accreditation Council.
