"I know Diane when she was working for ATAS UK and also as a consultant for the company NLisis. She has an extreme high level of knowledge in GC - GC x GC and GC-MS, and is next to that good in transferring this knowledge to other less skilled people in this profession. Also I must say that she is an very nice person to work with both as partner and as supplier."
