How much do bioanalytical mass spectrometry jobs pay per hour?

As of Aug 16, 2026, the average hourly pay for bioanalytical mass spectrometry in the United States is $22.62, according to ZipRecruiter salary data. Most workers in this role earn between $18.51 and $24.04 per hour, depending on experience, location, and employer.

What is bioanalytical mass spectrometry?

Bioanalytical mass spectrometry is a scientific technique used to identify and quantify chemicals, such as drugs and biomolecules, in biological samples. It combines the principles of mass spectrometry with bioanalytical chemistry to analyze complex biological matrices like blood, urine, or tissue extracts. This method is essential in pharmaceutical research, clinical diagnostics, and biomarker discovery due to its high sensitivity, specificity, and accuracy.

What are some typical challenges faced when working in bioanalytical mass spectrometry, and how can they be addressed?

Professionals in bioanalytical mass spectrometry often encounter challenges such as matrix effects, sample preparation complexities, and data interpretation of complex biological samples. Addressing these challenges involves optimizing sample clean-up procedures, regularly calibrating and maintaining instruments, and collaborating closely with colleagues in method development and validation. Staying current with new analytical techniques and software tools can also help in resolving technical issues and ensuring reliable, high-quality data for regulatory submissions or research projects.

What are the key skills and qualifications needed to thrive in bioanalytical mass spectrometry, and why are they important?

To thrive in Bioanalytical Mass Spectrometry, you need a solid background in analytical chemistry, biochemistry, and quantitative analysis, often supported by a relevant degree (such as a BSc, MSc, or PhD). Proficiency with mass spectrometry instruments (e.g., LC-MS/MS), chromatography systems, and specialized data analysis software is essential, and certifications in laboratory safety or GLP can be advantageous. Attention to detail, critical thinking, and strong problem-solving abilities help you interpret complex datasets and troubleshoot technical issues effectively. These skills are crucial for producing accurate, reproducible results that drive scientific discovery and support regulatory compliance in pharmaceutical, clinical, or research environments.

What is the difference between Bioanalytical Mass Spectrometry vs Analytical Chemist?

AspectBioanalytical Mass SpectrometryAnalytical Chemist
CredentialsBachelor's or Master's in Chemistry, Biochemistry, or related fields; certifications in mass spectrometryBachelor's or Master's in Chemistry or related fields; certifications vary
Work EnvironmentLaboratories focused on drug development, pharmacokinetics, or clinical researchGeneral laboratories, quality control, research and development
Industry UsagePharmaceutical, biotech, clinical researchPharmaceutical, environmental, food testing, academia

Bioanalytical Mass Spectrometry specialists focus on analyzing biological samples using mass spectrometry techniques, often within pharmaceutical and clinical settings. Analytical Chemists have broader roles in chemical analysis across various industries. While both roles require chemistry knowledge, bioanalytical mass spectrometry professionals specialize in advanced instrumentation and biological sample analysis, making their skills more specific to bioanalysis applications.

Scientist I - Mass Spec Development (LC-MS/MS)

KCAS Bio

Kansas City, MO • On-site

Full-time

Re-posted 29 days ago

Job description

Performing critical work that impacts our industry and our world’s health while problem solving and innovating in the field – that is what Scientists at KCAS Bio get to do every day. If that gets you excited too, then maybe working as a Scientist at KCAS Bio is the role for you.

When you work as a Scientist in the Mass Spec Bioanalysis Development group at KCAS, you get to further our mission by learning and applying your knowledge in bioanalytical and scientific principles to support study execution and development activities under the guidance of senior scientists. You will begin building your foundation in assessing data integrity and troubleshooting with support.

Our Mass Spec Bioanalysis Development team uses LCMS (Liquid Chromatography Mass Spectrometry) techniques to conduct sophisticated sample preparation to meet bioanalytical needs for drug discovery, preclinical, and clinical studies, including bioanalysis of drugs and metabolites, biomarkers, and active endogenous compounds in biological fluids and tissues.

In this role, we will rely on you to:
  • Execute assigned portions of studies including sample preparation (extractions, enrichments/affinity capture, digestions) and LCMS analysis under supervision
  • Support method development and qualification activities by following established protocols
  • Perform routine data processing and assist in preparing data summaries
  • Troubleshoot basic technical issues with guidance
  • Maintain accurate documentation in compliance with study protocols, SOPs & regulatory requirements
  • Ensure proper sample identification, handling, and tracking
  • Communicate progress and escalate issues to senior staff as needed
  • Perform all aspects of the job in a way that supports company brand and supports company mission, vision, and values
To qualify for this role, you will have:
  • Bachelor’s or master’s in chemistry, Biochemistry or chemical/biochemical engineering, or related field with 2+ years of experience with LC-MS/MS
  • Exposure to bioanalytical sample preparation and quantitative LC-MS/MS techniques (academic or industry)
  • Basic understanding of chromatographic principles and mass spectrometry
  • Experience with small molecule analysis; exposure to proteins and peptides is a plus
  • Familiarity with laboratory documentation and working in a structured or regulated environment is preferred
Depending on your background and qualifications, we may consider hiring you for one of three levels of Scientist roles at KCAS Bio. This will be determined during the interview process.  

(Please note this is a representative summary of responsibilities, not a comprehensive or exclusive list of the duties to be performed in any position. Employees must follow instructions and perform additional duties as requested.)

WHO YOU ARE
You will thrive at KCAS Bio if you enjoy a relational environment, are purpose- and values-driven, embrace constant development and supportive leadership, and enjoy being part of innovative work.
