The stainless steel sampling canisters and accompanying flow controllers and vacuum gauges were supplied by Quanterra Environmental Services (City of Figure 6 Comparison of SUMMA canister and charcoal tube analyses of paired samples. The intercept was not significantly different from zero (t Summa canister sampling instructions. Grab Sample Collection. 1. Remove the summa canister cap. Do not open the canister general permit is the annual collection and testing of grab samples from all systems . manufacturer's instructions to ensure equipment is properly calibrated. Pacific Northwest National Laboratory'") provided SUMMA"' canisters and sorbent traps for sample collection, and analyzed the samples according to instructions in the SAP (Buckley 1996). Analytical work was performed by the PNNL VAL in the 300 Area of. Summa canister sampling. 1.0 scope and application. The purpose of this standard operating procedure (SOP) is to describe a procedure for sampling of volatile organic compounds (VOCs) in ambient air. The method is based on samples collected as whole air samples in Summa The "SUMMA CANISTER" with a restricted flow orifice was used to collect and preserve "off-gas" vent samples from a landfill in Illinois. Since the method is rarely used for vent sampling, standard accepted methods were used to confirm the integrity of the technique. The technique presented some problems Canister Sampling Instructions. Time integrated samples. Grab samples. 1. Record the canister ID on the COC 2. Record the initial vacuum reading on the COC 3. Remove the brass dust cap with a 9/16" open. Canister and cartridge samples were analyzed in the trace gas laboratory at INSTAAR on a gas chromatography system. Stainless steel Summa canister with passive sampling flow regulator (right) and two solid adsorbent cartridges for VOC sampling (front left) shown side by side. What are Summa Canisters? A Summa canister is constructed of specially treated stainless steel designed for collecting a whole air sample. Compared to Tedlar® bags and Sorbent Tubes, a Summa canister is far superior to use and does not require a separate pump. (Summa canister) soil gas samples ( Fig. 3a and Table 2) had TCE concentrations ranging from 20 000 (one outlier excepted) to 55 000 Individual Summa canister samples showed differences of up to 20 000 mg m A3 from one sample to the next, which is a higher degree of variability than expected Silonite Canisters Silonite canisters represent the next generation of air sampling containers. Silonite is a unique fused silica coating that creates a smooth, siloxane-free Instructions for cleaning the Summa canisters are described in ERT/REAC SOP # 1703, Summa Canister Cleaning Procedures. Canisters for air sampling (often referred to as SUMMA® canisters) have long been used to monitor volatile organic 'air toxics'. Whole air canister sampling is a simple form of 'grab' sampling and is useful for sampling very volatile, non-polar compounds such as C2 to C12 hydrocarbons and the Air sampling can be more involved than water or soil sampling due to the reactivity of chemical compounds. This guide focuses on collecting a sample in the most common air sampling containers, Summa canisters and Tedlar(r) bags.
