Beyond the Job Description
Each day for an Analytical Chemist is a blend of meticulous lab work and data analysis.
Morning
The morning often begins with calibrating analytical instruments like GC-MS or HPLC to ensure accuracy and reliability. After calibration, the focus shifts to preparing samples for analysis. This might involve dissolving samples in appropriate solvents, extracting analytes of interest, or performing derivatization reactions.
Midday
The midday is typically dedicated to running samples on analytical instruments. This involves loading samples onto the instrument, initiating the analytical run, and monitoring the instrument's performance. Following the runs, raw data is collected and initially assessed for potential errors or anomalies.
Afternoon
The afternoon is primarily focused on data analysis using software like ChemStation or MassHunter. This includes peak integration, quantification of analytes, and validation of results. A significant portion of the afternoon is spent writing reports summarizing the findings and conclusions of the analysis.

David's Quick Thinking Prevents a Production Halt
David, working in a pharmaceutical manufacturing plant, noticed inconsistencies in the HPLC data for a critical intermediate. Instead of simply re-running the analysis, he thoroughly investigated the issue and discovered that a batch of the reference standard had degraded. He promptly notified the team, preventing the use of the compromised standard and averting a potential halt in production that could have cost the company hundreds of thousands of dollars. David's proactive approach and attention to detail saved the day.
Thorough investigation and proactive communication are crucial for preventing costly errors in analytical processes.
Emily's Method Validation Saves the Day
Emily, a senior analytical chemist, meticulously validated a new method for quantifying a novel drug candidate. During validation, she discovered a previously unknown interference from an excipient.
