The letter, part by part
Eva Edwards (Analytical Chemist, Contract Testing Laboratory) is applying to be a Senior Analytical Chemist at Lakeshore Polymer Labs. Here is what each paragraph does.

- The fit
- The close
Dear Hiring Manager,
Lakeshore Polymer Labs has a reputation across the Midwest for turning difficult formulation problems into reliable products, and your recent work on recyclable packaging resins is the kind of chemistry I want to be part of. I am applying for the Senior Analytical Chemist position because it combines method development with direct, hands-on support for your formulation teams.
In five years at a contract testing laboratory, I have developed and validated 14 HPLC and GC methods for clients in coatings and adhesives. One method I built for residual monomer analysis cut run time from 38 to 22 minutes, freeing about six instrument hours per week. I also coordinated our move to an electronic lab notebook, which reduced data review errors by roughly 30%.
Your role calls for strong chromatography, spectroscopy, and the ability to explain results to non-chemists. Beyond HPLC and GC-MS, I regularly use FTIR and DSC to characterize polymers, and I present monthly data summaries to client project managers. I mentor two junior analysts and enjoy building tidy, well-documented methods that others can run confidently without me in the room.
I would appreciate the opportunity to discuss how my method development experience could support your packaging program and help your formulation teams move faster with confidence in their data. I can share redacted validation reports on request and am available for an interview any weekday. Thank you for your time and consideration.
Kind regards,
Eva Edwards
Skills to mention
Employers hiring a chemist often look for these. Name the ones you really have, with an example.
Phrases you can borrow
Change the details to your own, then copy them into your letter.
I design methods with the next analyst in mind, so procedures are robust, clear and easy to transfer.
I enjoy translating complex spectra and chromatograms into decisions a formulation team can act on.
I balance speed with rigor, validating every method to the standard the data will ultimately be judged by.
I take ownership of instrument uptime and troubleshoot problems before they delay project timelines.
Tips for a chemist cover letter
- List the analytical techniques you have validated, not just used, to signal seniority.
- Quantify efficiency gains such as run time, throughput or instrument hours saved.
- Show that you can explain data to non-chemists, since senior roles involve client or team communication.
- Mention mentoring or training if you are applying for a senior position.
- Respect confidentiality: describe client work by industry, never by client name.
Mistakes to avoid
- Listing every instrument you have touched instead of the techniques you have truly mastered.
- Sharing confidential client names or proprietary results in your letter.
- Leaving out communication skills when the role involves supporting other teams.
