Abstract
Once a heat transfer fluid (HTF) has been sampled it is chemically analysed according to defined international standards. However, the technique for sampling can vary from organisation to organisation. The impact of sampling technique is explored in the current report as its impact on subsequent test results is not widely acknowledged even though chemical analysis in the laboratory occurs sometime after the HTF has been sampled at the client’s site. Data is presented to show that the closed sampling of mineral-based HTFs is important in gaining a representative HTF as it helps to prevent light-chain hydrocarbons escaping from the sampled HTF. When taking a closed sample from an operating plant, repeated analyses should be conducted on samples and multiple samples should be taken on each visit and this should be repeated regularly throughout the year as part of a HTF condition maintenance programme. The current report highlights the importance of gaining both a representative sample and repeated laboratory analyses in order to maintain a safety and effective plant.
