In this internship, my company of attachment is Chevron Singapore, Laboratory (Lubricants Department), as a Lab Analyst intern. As an intern, my duties are to do lab testing, as well as relevant paperwork involving Statistical Quality Control testing.
Additionally, as shift work is a requirement for Lab Analysts, I will be helping the Analyst I am attached to for shift work in some tests such as the Analysis of Metals via Inductively Coupled Plasma Atomic Emission Spectrometry, and Density, the methods of which will be discussed below.
As an intern, it is imperative for me to be able to understand the duties of a Lab Analyst within the internship period and to be able to maintain requirements expected of myself. Thus, this report…show more content… 2. Introduction

Other than SQC, equipment calibration is done at regular periods of time in order to ensure that the equipment is able to give the correct and accurate range of values; for example, mass balance calibration is done every day, using a standard mass of exactly 200g. If an equipment is found to be faulty and servicing is to be done, calibration is done by using SQC standards, to allow for the equipment to be able to measure accurately the required parameters.
Some of the methods of testing requires a period of training to ensure competency, for example, D5185, which tests for the concentration of various metals such as calcium and zinc via Inductively Coupled Plasma Atomic Emission Spectrometry (ICP) within an oil sample, and D892, which tests for the foam characteristics of a
