Bayanda Shange

Analytical Chemistry professional with over 1.5 years of laboratory experience, including independent petroleum and lubricant testing, kinematic viscosity, density, cloud point, corrosion, and grease testing. Experienced with ASTM D1121, D445, D892, D1293 and D4052; SVM, viscometers and grease-testing instruments; sample traceability, calibration records, QC data and more than one hundred COAs per week. Strong practical background in GLP, product investigations and laboratory reporting.

LABORATORY ASSISTANT at GEOCHEM (2026-04 – Present)

• Independently perform petroleum and lubricant testing, including kinematic viscosity, density, cloud point, total alkalinity, crackle, filter paper corrosion, and copper corrosion tests.
• Apply ASTM D1121, D445, D892, D1293 and D4052 and operate SVM, viscometers, TDS meters, and grease-testing instruments.
• Generate and distribute more than one hundred Certificates of Analysis per week, maintaining accurate and traceable laboratory records.
• Receive and test raw materials against supplier COAs and assess finished products against approved specifications.
• Maintain sample retention, equipment checks, calibration worksheets, batch records, and QC results in Excel.
• Independently investigated a recurring product separation issue and revised mixing instructions so the product could be made using the original raw-material quantity rather than approximately three times the initial quantity; recurring separation ceased after implementation.

LABORATORY TECHNICIAN INTERN at GEOCHEM (2025-04 – 2026-03)

• Performed raw-material sampling and routine product testing in a QC laboratory.
• Managed sample retention, sample identification, and storage; coordinated external laboratory submissions and captured returned results.
• Followed SOPs and GLP requirements while maintaining housekeeping and chemical storage standards.
