Our analysis department

This department is our core business. Every employee has a specific mission:

Every employee has a specific mission :

Laboratory assistants receive and register samples in compliance with the clients’ analysis requirements

The chemist-technicians who are accredited for the requested analyses then analyse the sample and reprocess the results

Finally, the laboratory manager or their deputy checks the reports, validates them and sends them to the clients.

The laboratory: an autonomous and complementary team

“At Quad-Lab, the technicians work both autonomously and in teams, as they complement each other.   Each person is assigned a portfolio of analyses. Then each team member organises their work to meet the announced deadlines.

If there is a large amount of work, or if there is an emergency, the team has the capacity to take on extra workloads, since every technician is accredited for all the analyses and all the techniques. Our greatest satisfaction is to see processing lead times drop so that we often manage to deliver the analysis early! “

David Escudeiro, analysis department manager

Our customer department

The Customer Department has a central role in Quad-Lab.

Its mission is to :

Examine each client request and provide a solution within 24 hours

Give each client a customised service using a single contact throughout the mission

A privileged contact will be in charge of accompanying you in each phase, and will inform you in real time on:

  • the study of your needs in order to advise you on the most suitable sampling equipment and analyses
  • the drawing up of the quote
  • depending on the case, the shipment of the suitable sampling equipment
  • tracking the processing of your samples until they are analysed
  • sending your results
  • answering eventual questions following the analyses

Our Customer Department is also available for specific situations such as :

Emergency analyses

Depending on your requirements, it can examine a proposal for an emergency analysis (within less than 10 working days). These will be delivered within the announced deadlines in 100% of cases.

Non standard or bespoke analyses

If a type of analysis is not featured in the catalogue, a bespoke analysis proposal can be made. All questions concerning feasibility will be answered in under 24 hours.

Our Customer Department never leaves a client without a solution. If the laboratory is unable to fulfil a request, you will be directed to a laboratory or partner that can do so.

“Customer satisfaction is one of Quad-Lab’s fundamental values”

Julie Langlet, Customer Department manager
