GC_EV1252 Maxxam Analytics HRMS Group Receives Kaizen Award for Productivity Improvements Congratulations to Maxxam Analytics’ Hi-Res Mass Spec Ultra Trace Analysis team, who received a Kaizen award for productivity improvements made using the Rtx®-Dioxin2 column. Shown from left to right are: Owen Cosby, Supervisor HRMS Services; Kay Shaw, HRMS Team Leader and Scientific Specialist; and Angel Guerrero, HRMS Senior Analyst. According to Owen Cosby of Maxxam Analytics, “Using the Rtx®-Dioxin2 column allowed us to combine EPA 1613 TCDD-only and TCDF confirmation analyses onto one column and one instrument. This resulted in multiple benefits— we shortened run times, reduced instrument downtime and column changes, and increased instrument capacity for our full-list samples.” www.restek.com 587
