LC Technology study guide
LC Technology · Work through your exam, one topic at a time.
LC Technology is a professional certification exam for people who work with liquid chromatography in analytical laboratories - bench analysts, method development scientists, QC reviewers, and instrument owners who need to demonstrate applied competence rather than recall of a single vendor's software. The exam is delivered as multiple choice and is organized around seven content areas: laboratory safety and regulatory compliance; LC fundamentals and separation theory; instrumentation and system components; method development and optimization; sample preparation and injection; data acquisition, integration, and quantitation; and troubleshooting and maintenance. The LC Technology study guide has 7 sections and about 2,484 words.
01Laboratory Safety and Regulatory Compliance
This domain tests the daily decisions an LC analyst makes with solvents, waste, and records: which operations need a fume hood, how mobile phase waste is segregated, and what makes an electronic result defensible in an audit. Items are usually scenario-based - a spilled buffer, a nearly full waste carboy, a re-integrated chromatogram - and the correct answer must satisfy both the regulation and the chromatography.
401 words, about 2 min02Liquid Chromatography Fundamentals and Separation Theory
This domain tests whether you can explain and predict retention. Expect questions on retention factor, selectivity, plate count, resolution, isocratic versus gradient behavior, and how pH, organic modifier, and temperature shift a separation.
358 words, about 2 min03Instrumentation and System Components
This domain tests your mental model of the flow path: solvent delivery, degassing, sample introduction, separation, detection, and the data system. Questions ask which component causes a symptom, or how a hardware parameter changes the chromatography.
358 words, about 2 min04Method Development and Optimization
This domain tests how a method is built and adjusted deliberately. Expect questions on column and mobile phase screening, pH and solvent choice, gradient design, robustness, forced degradation, and the adjustments permitted under USP <621 .
329 words, about 2 min05Sample Preparation and Injection Techniques
This domain tests what happens before the sample reaches the column: diluent, clean-up, concentration, and the injection itself. Many so-called chromatographic problems - split peaks, carryover, poor precision - originate here.
336 words, about 2 min06Data Acquisition, Integration and Quantitation
This domain tests the chain from detector signal to reported number: sampling rate, integration, calibration, and the integrity of the record. Set data rate from the narrowest peak, not the run length.
346 words, about 2 min07Troubleshooting and Maintenance
This domain tests systematic diagnosis. The exam rewards a logical order - is the problem pressure, retention, peak shape, or signal?
