Introduction  \nThe technology used in personal sampling pumps has not changed much over the past 20 years.  \n􀁸 There are still battery life/memory problems associated with Nickel Cadmium (NiCad) rechargeable batteries.  \n􀁸 Pre-and post-flow rate measurements are still conducted today. These measurements are based on calibration procedures that were established in the late 1960s and early 1970s, prior to even “Back EMF Flow Control” use in air sampling pumps.  \n􀁸 Comprehensive, consistent reporting and data management have always been a time-consuming recordkeeping process.  \n􀁸 With the introduction of programmable data logging pumps the need to interface with them is necessary to utilize them to their full potential.  \n􀁸 The complexities associated with low flow sampling using a high flow pump have been around since the beginning. An external low flow adapter must be used to put the pump into a constant pressure condition and it is simply assumed that the low flow adapter flow rate remains constant while sampling is conducted.  \nII. Smart Battery Management System ™ Technology  \nKnowing how much battery runtime is available under actual operating conditions when sampling is crucial to ensure completion of samples. It is not an easy task to determine pump runtime from a pump performance curve and percent battery life (a measurement of battery voltage) remaining on a pump. Many samples are never completed due to the batteries not having enough runtime charge capacity to run for the intended duration of the sample. Charging times for the widely used NiCad battery technology are long and single and multi-unit chargers are expensive.  \nSIDEPAK, TRAKPRO, Smart Battery Management System, and TSI logo are  \ntrademarks of TSI Incorporated. TSI is a registered trademark of TSI Incorporated.  \nTSI® designed the “Smart Battery Management System™” technology, that allows you to see remaining runtime in minutes right on the pump screen under actual sampling conditions. This new battery system is based on a battery charge capacity measurement in milliamps (mA), not a simple and unreliable battery voltage measurement. As a NiCad battery decays, its battery curve flattens out after about an hour of discharge and remains that way through most of the battery’s discharge cycle (see Figure 1) . This results in a very misleading reading of percent battery remaining with battery voltage as the measurement.  \nFigure 1 – Battery Decay Curve  \nThe Smart Battery Management System ™ technology uses a microprocessor in the battery pack that measures the battery’s charge state (mA) and total charge capacity. It measures the current rate of drain (mA) on the battery under actual sampling conditions (flow rate and back pressure) to show how long (in minutes) the battery can deliver. Have you ever had a pump do that for you before?  \nThe most commonly used battery technology is NiCad, and it has memory and charging time issues. TSI SIDEPAK™ pumps use Nickel Metal Hydride (NiMH) battery technology that does not have the memory and charging issues associated with NiCad batteries. TSI has put the battery charging circuitry inside the pump so that an external power supply is all that is needed to charge the battery. And there are multiple NiMH battery options as well.  \nThere are very few Industrial Hygienists who have not lost a sample due to NiCad batteries that have developed a memory and no longer have enough runtime charge capacity to complete that sample. It’s time consuming and costly to lose samples.  \nLet’s take a look at the approximate time and cost of an incomplete sample. This is based on conducting three samples per work shift and the Industrial Hygienist’s time through determination of the sample failure.  \nTime  \nIH Lab consult =  \nPre-Calibration of pump (including prep time for calibration standard) = Selection and preparation of sample media from IH Lab =","cbCaiqGlQNQjuSEm","https://ap.wps.com/l/cbCaiqGlQNQjuSEm","pdf",405820,"English","# I.
