Numerical modelling and calculation were used to show the performance of the chiller with different adsorber tube diameter. Heat and mass recovery were adopted in order to increase the cooling capacity. ![]() The design configuration is composed of two sorption chambers with compact fin tube heat exchangers as adsorber, condenser, and evaporator. Budiman, D.Ī new design of silica gel-water adsorption chiller is proposed. Simulation of adsorber tube diameter's effect on new design silica gel-water adsorption chiller The centrifuge is hand-operated and is ideal for short spin down purposes. It can accommodate 2 standard size 96-well plates or 24 strips or up to 192 microfuge tube. ![]() It was made using a salad spinner and two polymerase chain reaction (PCR) tubes racks. We report a practical home-made microcentrifuge to be used for teaching purposes. (author)Ī Practical Home-Made Microcentrifuge for Teaching Purposes ![]() The home-made SPME adsorbent was shown to be a good alternative to commercially available fiber for the determination of accelerants in arson cases. The homemade fiber was also applied for the simulated arson samples. Compared with commercial PDMS/ DVB fiber, the new homemade fiber exhibited higher extraction capability and good selectivity for accelerants. Poly dimethylsiloxane divinylbenzene (PDMS/ DVB) is the most common fiber coating for the extraction of hydrocarbon compounds. The efficiency of the new fiber coating prepared by sol-gel technology for the determination of accelerants was compared to that of commercial PDMS/ DVB fibers. A new fiber prepared by sol-gel method, containing 1:1 molar ratio of octyltriethoxysilane (C 8 -TEOS): methyltrimethoxysilane (MTMOS) was employed in this technique. This paper presents a simple, fast, effective and environmental friendly methodology for the determination of accelerants in arson samples using headspace solid-phase micro extraction coupled to gas chromatography. Umi Khairul Ahmad Abdul Rahim Yacob Selvaraju, GeethaĪ number of adsorbents are available commercially as coatings for SPME fibers but some analytical methodologies might demand specific properties for the extraction of selected compounds, special coatings that have particular volume and a selectivity towards particular analytes.
