等速抽样
Apex Instruments Inc. offers a wide array of equipment and supplies for sampling stationary source emissions for pollutants in accordance with US EPA Reference Methods. Most of the methods are generally classified as either Isokinetic or Gaseous Sampling Methods. This section includes Apex Instrument Isokinetic equipment and accessories. This type of sampling requires the sample to be drawn from the gas stream at the same rate it is moving through the stack or duct.

Apex Isokinetic Source Sampler systems let the operator monitor gas velocities, temperatures, pressures and sample flow rates for maintaining isokinetic sampling conditions. The Source Sampler system is easily adapted to test for a wide range of pollutants from stationary sources, such as dust including particle size distributions, metals, polychlorinated biphenyls (PCBs), dioxins/ furans, polycyclic aromatic hydrocarbons (PAHs) and an ever increasing group of pollutants tested for with adaptations of this basic isokinetic test method.
Our Isokinetic equipment is designed to be modular, where you choose your meter console, pump and components of choice to meet your particular needs.

方法5
固定来源的颗粒物排放 - 专业的来源抽样公司必须为各种条件和位置做好准备。Apex建议使用“ Deluxe Plus”系统，可以在刚性和灵活的配置中使用。即使有经典的刚性布置，其他玻璃器皿也可以使您可以预先测量和填充的撞击器，预先兑换过滤器组件以及两次运行之间的最小周转时间。
方法17
通过堆栈过滤的颗粒物排放 - 在方法5系统中添加堆栈内滤波器组件和更长的皮托尖端。Apex网站首页 Instruments方法17采样套件是用于采样颗粒物的方便包装。
方法23
Dioxins / Furans – The Apex Instruments Method 23 (Modified Method 5) Source Sampler Kit is used for determination of dioxins and furans (D/F’s) in accordance with Method 23 and/or Determination of Semi-Volatile Organic Compounds as M0010. This train adds a water-cooled glass condenser, an XAD adsorbent module, and a large capacity METHOD 23 knockout impinger to the Method 5 system.
方法26a（HCI）
Hydrogen Halide & Halogen Emissions – the M26A kit adds impingers, reagents, and PTFE coated glass filters to a Method 5 train. The Apex Instruments Method 26A Sampling
火车用于测定卤化氢和卤素的排放。方法26a是方法26的同动替代方法。该方法特别适合通过发射酸液滴控制的湿洗涤器控制的采样来源。
方法29（多种金属）
金属排放量 - 加起来三个撞击器，即SB-4阻碍案，玻璃喷嘴，探针衬里和非金属联合到Method 5火车。该方法已被验证，用于收集17种不同的金属。
METHOD 201A
粒度 - 在方法5系统中添加旋风。方法201a的目的是测量颗粒物排放等于或小于标称空气动力学直径（S）。通常，从固定燃烧源以预定的恒定流速通过堆栈内尺寸设备提取气体样品。修改后，方法201A现在将现有方法（PM10）与PM2.5旋风结合在一起，以创建一个抽样列车，其中包括两个旋风。
方法202
可冷凝的颗粒物(CPM), Dry Impinger Method – This isokinetic method is used to measure Condensable Particulate Matter (CPM) from stationary source emissions after particulate matter has been removed by a heated filter, such as in Method 5, 17 or 201A. The CPM is collected in dry impingers maintained at 80°F.
