On 8 October 2025, PhD student Luka Čotić (DOK-NPOO-2023-10-7422) took part in the GC Masterclass Workshop held at the Bicro Biocentar facilities in Zagreb. The workshop was organised by Anas d.o.o. and delivered by Jaap de Zeeuw, a renowned international expert in gas and liquid chromatography.

During the workshop, Luka had the opportunity to gain deeper insight into common challenges related to sample preparation and injection into the column, as well as the importance of regularly replacing consumable parts—such as septa, liners, seals and ferrules—to ensure stable and reliable analytical performance, especially for the BeerBy-4-OliveFly project (HRZZ-IP-2022-10-9643).

In addition to practical guidance, he acquired essential knowledge on improving peak shape and reducing noise levels in GC and GC-MS techniques. The workshop also emphasised strategies for developing and optimising new analytical methods, offering valuable insights for future laboratory work and enhancing the quality of ongoing research.
