Essential Oils Application Days

Following ISEO 2026, LECO invites attendees to join us for an exclusive, application-focused program in Grasse, on Wednesday afternoon, 9 September, and Thursday morning, 10 September.

These flexible, appointment-based sessions are designed to offer a more in-depth, personalized continuation of discussions initiated during the conference.

Participants will have the opportunity to submit one sample in advance for consideration. Selected samples will be analysed by LECO specialists prior to the event using one of two turnkey approaches:

  • Qualitative Characterization using the Pegasus BTX
    • GC-TOFMS analysis for deeper insight into sample composition.
  • Automated Reformulation support using the Pegasus BTX4D with Paradigm and Shift
    • GCxGC-TOFMS/FID analysis for more detailed comparative and formulation-based investigations.

During the in-person session, LECO specialists will present and discuss the results directly with participants, connecting the data back to their specific samples, current analytical challenges, and project goals.

Additionally, attendees can register for an individual presentation on “All Allergens in One Turnkey Analysis with LECO”.

Submitting a Sample

Sample analysis will be conducted at LECO’s European Application and Technology Center (EATC) in Berlin. Participant’s sample should be provided ready to inject, and the sample must reach the EATC before 6 August 2026.

Hazardous samples require relevant SDS/MSDS documentation, and customers shipping from outside the EU should discuss shipment details with their local LECO representative.
