Method 201A: Determination of PM10 emissions (constant sampling rate procedure)

Draft Method 201B: Determination of PM10 and PM2.5 emissions (constant sampling rate procedure)

PM10-SS Cyclone and Nozzle Set

The ESC PM10 Cyclone and Nozzle Set is manufactured to the interior dimensional specifications defined by the USEPA in Method 201A for in-stack measurement of particulate matter 10 microns and less. Sets are available in stainless steel and Teflon-coated stainless steel and include the cyclone body, 11 nozzles and a 47mm in-line filter holder in a foam-lined case. The filter holder outlet mounts directly to a standard Method 5 probe assembly. The PPS12-Y-PM10 Modular Type S Pitot Tip is required to extend the pressure planes even with the cyclone inlet nozzle.

 

PM2.5-SS Cyclone and Nozzle Set

The ESC PM2.5 Cyclone and Nozzle Set is manufactured to the dimensional specifications defined by the USEPA and Southern Research Institute originally published in the Application Guide for Measurement of PM2.5 [and less] at Stationary Sources. The Set is available in stainless steel and Teflon-coated stainless steel and includes the cyclone body, 6 nozzles and a 47mm in-line filter holder in a foam-lined case.

PM10-2.5-SS Combination PM10 and PM2.5 Cyclone and Nozzle Set

The draft method for determination of PM10 and PM2.5 specifies the procedure for simultaneous in-stack segregation of particulate matter greater than PM10, equal to or less than PM10 but greater than PM2.5, and equal to or less than PM2.5. The particulate matter is recovered from three clearly defined zones within the dual cyclone assembly. Each PM10-25-SS combination set includes a PM10 cyclone, 11 PM10 nozzles, a 47mm filter assembly, a PM2.5 cyclone, the cascade adapter linking device and full assembly support cradle.

VOST: Determination of volatile organic compounds in gaseous emissions from stationary sources (SW-846 Methods 0030 and 0031)

V-S1 Single VOST and V-S2 Dual VOST Samplers

The ESC Single and Dual VOST (Volatile Organic Sampling Train) Samplers are used in conjunction with the UNI-VOS-110 Low Flow Control Console to perform SW-846 Methods 0030 and 0031. Volatile organic compounds in the sample stream are passed through a Pyrex coil condenser followed by cartridges packed with Tenax, Tenax/charcoal or Anasorb adsorbent material. The cartridges are thermally desorbed prior to analysis of the volatile organics by gas chromatography/mass spectroscopy.

The V-S1 Single VOST Sampling System uses a single glassware set. The V-S2 Dual VOST Sampling System holds two glassware sets in a single caddy with a 4-way valve at the outlet end to allow continuous sampling. After a sample run the valve can be switched to the other glassware set for sampling while sorbent cartridges in the first set are changed and leak check is performed. Two separate pumps in the UNI-VOS-110 Console with dual pump option allow simultaneous sampling and leak checking.

UNI-VOS-110 Low Flow Control Console

The UNI-VOS-110 is the ideal Metering Control Console for accurate volume measurements in low flow gas sampling methods requiring sample rates from 0.5 to 2 liters per minute. The flow rate adjustments, gauges and temperature readouts on the console and the 0.01 Liter resolution of the dry gas meter allow the tester to maintain a constant and accurate flow rate while monitoring gas meter pressure and temperature and five remote temperatures. Two digital temperature controllers are provided for maintaining probe and filter heat.

Alternatively the C-5000 Isokinetic Control Console can be used with an appropriately sized CO-FA style Orifice Flow Adapter.

Method 0061: Determination of hexavalent chromium from stationary sources

HC-S1 Hexavalent Chromium Isokinetic Sampler

The ESC HC-S1 Hexavalent Chromium Isokinetic Sampler is designed to aspirate the potassium hydroxide impinger solution behind the nozzle in order to impede molecular changes to the hexavalent chromium once sample is drawn from the source. The Sampler includes a heated, Teflon lined, isokinetic probe assembly with recirculating nozzle union, PFA Teflon Impinger Set, peristaltic recirculating pump, insulated cold box with probe support adapter and pump shelf, umbilical adapter with power distribution box and a PFA Teflon filter column. The filter column is used for filtration of hexavalent chromium samples prior to analysis.

The HC-S2 High Temperature Hexavalent Chromium Isokinetic Sampler

The HC-S2 High Temperature Hexavalent Chromium Isokinetic sampler is recommended for use on sources with temperatures above 300°F. This sampler replaces some Teflon components with either Pyrex or Quartz alternatives in order to eliminate exposure of Teflon components from the probe assembly and potassium hydroxide recirculation lines to the elevated stack temperature.

NCASI Method 8A: Determination of sulfuric acid vapor or mist and sulfur dioxide emissions from kraft recovery furnaces

The ESC controlled condensate system utilizes a high temperature oven to house a thimble filter holder followed by a heated coil condenser that is carefully temperature controlled within very narrow tolerances to achieve separation of sulfuric acid vapor or mist (including sulfur trioxide) and sulfur dioxide. Both fractions are measured separately by the barium-thorin titration method. The system includes a heated quartz lined probe and high temperature oven each capable of maintaining 550°F, quartz thimble filter holder, Pyrex coil condenser with thermocouple port on recirculation jacket, Pyrex condenser exit adapter with thermocouple port and heated water bath with recirculating pump. The oven is equipped with hanging brackets, a probe support bracket on the inlet end and a condenser cradle on the outlet end so that all glassware is protected and securely supported. A flexible transfer line is used to carry the separated sample to a chilled Pyrex 3-impinger set.
