Chemical Analyses

Science Laboratory Technology · Level 6  ·  4 Chapters

▣ What this unit covers

In this unit, you will be able to confidently perform a range of chemical analyses by selecting the right tests, safely collecting and preparing samples, and accurately handling reagents and equipment. You’ll master key laboratory techniques like titration and gravimetry, ensuring precise results every time. By the end, you’ll be ready to apply these skills in real-world settings, delivering reliable data that meets client needs with professionalism and care.

■ Where this takes you

In this unit you’ll learn how to turn a client’s question into a reliable chemical answer - a skill that powers many of Kenya’s essential industries, from safe drinking water to high-quality food and medicines. Whether you join a large laboratory or start your own testing service, the ability to plan, execute and document precise analyses will open doors to stable jobs and entrepreneurial opportunities.

  • Quality-control laboratories in tea and coffee factories in Kericho and Nyeri - you decide which analysis (e.g., moisture, pesticide residues) the client needs, set up the sampling tools, prepare reagents, run titrations or gravimetric tests, and record the results that certify each batch, earning a salary as a QC analyst.
  • Pharmaceutical manufacturing plants in Nairobi’s industrial zones - you assemble glassware, calculate exact reagent concentrations using the mole concept, perform titrations to verify active-ingredient potency, and document batch records that meet regulatory standards, earning wages as a laboratory technician.
  • Water-treatment and supply companies serving towns such as Kisumu, Mombasa and Nakuru - you collect water samples safely, determine chlorine or hardness levels by titration, prepare and store reagents on-site, and issue compliance reports that keep communities safe, earning either a staff position or contract fees for each sampling round.
  • Environmental monitoring units of county governments in rural districts - you gather soil and river samples, choose gravimetric or titrimetric methods to detect heavy metals or nutrients, process the results, and write clear field reports that guide local conservation plans, earning a stipend as a field analyst.
  • Food-safety testing labs serving smallholder dairy farms in Nakuru and Kiambu - you identify the required tests (e.g., antibiotic residues), collect milk samples, prepare standard solutions, carry out accurate titrations, and issue certificates that allow farmers to sell to formal markets, earning as a freelance lab technician or lab-owner.
  • Mining processing plants in Kitale, Eldoret and Kitui - you perform gravimetric analysis to determine ore grade, assemble the necessary apparatus, calculate reagent amounts, and produce detailed reports for mine managers, earning a salary as a chemist in the extraction sector.
  • Clinical chemistry sections of county referral hospitals in Eldoret, Machakos and Garissa - you prepare reagents for blood electrolyte or glucose tests, run titrations, document patient results in the laboratory information system, and support doctors’ diagnoses, earning as a laboratory technologist.
  • Forensic analysis units attached to police headquarters in Nairobi and other major towns - you collect trace evidence, apply gravimetric and titrimetric techniques to identify unknown substances, and write precise analytical reports that become part of legal investigations, earning as a forensic chemist.
  • Independent mobile testing services for artisanal gold miners in Kakamega and Vihiga - you travel to mining sites, collect ore samples, set up portable titration kits, calculate concentrations on the spot, and charge miners for each analysis, turning your laboratory skills into a thriving micro-enterprise.
  • Agricultural extension laboratories in Embu and Meru - you help smallholder farmers determine the exact composition of fertilizers, prepare reagents, run gravimetric analyses, and advise on optimal application rates, earning either a government salary or consultancy fees for each advisory session.

Mastering these techniques means you can guarantee quality, safety and compliance across Kenya’s most vital sectors - and you’ll have the confidence to create your own niche wherever precise chemistry is needed. Keep experimenting, keep documenting, and the opportunities will follow.
