摘要： Particulate concentration of diesel exhaust is measured by collecting the diesel particulate on a filter (18) while measuring the amount of exhaust passing through the filter (18). The filtered particulate is then heated in an oxygen rich environment (32) to oxidize carbon within the particulate to carbon dioxide. The amount of resulting carbon dioxide is measured in meter (38) to derive a corresponding measurement of the amount of filtered particulate. Particulate concentration is calculated by comparing the amount of exhaust passed through the filter. Filtered particulate can be heated incrementally to obtain a measurement of volatile components within the particulate prior to the oxidation of the non-volatile carbon component. The filter (18) employed to collect the particulate is of a high temperature resistant type making it reusable and can be either integral with or inserted into the oxidation chamber of the instrument. Oxidation of the particulate inherently concurrently cleans the filter for reuse.

摘要： Improved shaped glass elements (14, 16, 18, 20) having very low thermal coefficients of elastic modulus are provided for use as measuring means in balances for determining the mass of objects with a high degree of resolution. A particularly preferred form of the invention is fabricated from a glass consisting of 60.98 % SiO2, 14.7 % B2O3, 8.94 % Al2O3, 4.72 % Na2O and 10.9 % BaO, by weight.

摘要： Carbon particulate concentration of diesel exhaust or other sampled gas is measured by collecting the particulate on a high efficiency filter (18) while measuring the amount of sampled gas passing through the filter (18). The filtered particulate is then heated in an oxygen rich environment (16) to oxidize carbon within the particulate to carbon dioxide. The amount of resulting carbon dioxide is measured with a closed measurement loop (30) to derive a corresponding measurement of the amount of filtered particulate. Particulate concentration is calculated by comparing the amount of carbon particulate with the measured amount of sampled gas passed through the filter. Filtered particulate can be heated incrementally to obtain a measurement of volatile carbon components within the particulate prior to the oxidation of the non-volatile carbon component. The filter (18) employed to collect the carbon particulate is of a high temperature resistant type making it reusable and can be either integral with or inserted into the oxidation chamber (16) of the instrument. Oxidation of the particulate inherently concurrently cleans the filter (18) for reuse. An upstream preseparator (15) can extend the life of the high efficiency filter (18). Particulate can also be collected for analysis by using an accelerating impaction nozzle (68) in conjunction with a heatable impaction plate (70).
摘要翻译：通过在测量通过过滤器（18）的取样气体的量的同时将颗粒收集在高效过滤器（18）上来测量柴油机废气或其它采样气体的碳颗粒浓度。然后将过滤的颗粒在富氧环境（16）中加热以将颗粒内的碳氧化成二氧化碳。用闭合的测量回路（30）测量所得二氧化碳的量，以得出过滤颗粒的量的相应测量值。通过比较碳颗粒的量与通过过滤器的取样气体的测量量来计算颗粒浓度。过滤的颗粒可以被递增地加热以获得在非挥发性碳组分氧化之前颗粒内的挥发性碳组分的测量。用于收集碳颗粒的过滤器（18）具有耐高温型，使得其可重复使用，并且可以与仪器的氧化室（16）成一体或插入到该氧化室中。颗粒的氧化固有地同时清洁过滤器（18）以便重新使用。上游预分离器（15）可以延长高效过滤器（18）的寿命。还可以通过使用加速冲击喷嘴（68）与可加热冲击板（70）结合来收集颗粒以用于分析。
