Collection off-site analysis

In order to have sufficient sample material for onsite and off-site analysis, OPCW procedures recommend collecting the amount of sample material listed in Table 3 ... 

The ISP has the right to retain portions of all samples taken or to take duplicate samples (CWC VA Part II paragraph 54) therefore, any sample collected during an inspection is split into several fractions. In case of off-site analysis, split portions of the respective sample are sent to a minimum of two designated laboratories. These split portions are prepared, packed, and sealed on site during the inspection and are only opened at designated laboratories. 

In the case of equipment for the collection, preparation or analysis of samples, the inspection team will retain only data relevant to the purpose of the inspection. It is understood that in the case of negative results of the analysis in terms of the presence of chemicals searched for in accordance with the provisions of the Convention, the respective sample, computer file and any print-outs will be considered not relevant in the terms of the inspection mandate. This is without prejudice to both the right of the inspection team to transfer a sample for off-site analysis and the rights of a State Party in the case of a challenge inspection.

The sample quantities to be collected should be sufficient for a replicate analysis. However, alternative plans for sampling can be implemented. For example, a homogenized sample can be divided for on-site analysis, archival, and also to have a portion sent for orthogonal analysis to an off-site lab. 

Some concentrated nitric acid may be produced as a by-product in the SILVER II process when processing energetics compounds, which contain nitrogen. The material will be collected and sold to off-site users. During Demo II testing, analysis of nitric acid samples by the Ensign-Bickford Company determined that the... 

Chemical Weapons Convention Chemicals Analysis discusses sample collection, sample preparation and analysis, and concentrates on verification that takes place on site, analyses off site, and methods and procedures used. In the first part of the book is discussed the mobile laboratory of the OPCW and instrumentation and software used therein, as well as other on-site analysis equipment, procedures, and strategies. The OPCW gas chromatograph-mass spectrometer for on-site analysis is described and... 

The CWC describes the general responsibilities for sampling, sample transport to the off-site DLs, confidentiality of samples, sample analysis, and compilation of the report of analysis results of laboratories (1). The Verification Annex of the CWC, Part II, General Rules of Verification, paragraph E, Conduct of Inspections, and subparagraph Collection, handling and analysis of samples, and paragraphs 52-58 read as follows ... 

Detailed site assessments historically required extensive data collection and off-site laboratory analysis of contaminants. These studies are expensive and time consuming. Often, a suite of samples taken during site assessment shows unacceptable levels of contamination, requiring a second or even third round of sampling to determine the dimensions of contaminated areas. These multiple deployments increase both the time and costs associated with site assessment, reducing the resources available for cleanup. 

An initial plan for sampling at the site was developed. This plan would have required two mobilizations to collect soil samples at 20 locations to confirm the presence or absence of contamination where previous reports had implied potential source areas (US EPA, Office of Solid Waste and Emergency Response, 2004). All samples would be sent off-site for analysis. The total costs for this assessment were estimated at 203,000. 

At the beginning of the Triad field investigation, only the uppermost two 1 -ft intervals at each location were analyzed in the field. Ultraviolet fluorescence test kits, which require 5 min per sample for collection and analysis, were used for field detection of PAH and TPH at all sampling locations. A percentage of the PAH and TPH samples were sent to an off-site laboratory for independent collaboration of the field results. 

RCRA-regulated facilities operated by the Dow Chemical Company characterize all hazardous and nonhazardous wastes generated on-site or received from off-site locations according to a waste analysis plan as required by RCRA and prepared in accordance with federal and state regulations.28 The waste analysis plan is a part of the RCRA permit for the facility and describes the procedures used to collect information needed for the storage, treatment, and disposal of waste either on-site or at an off-site facility. Specified in the waste analysis plan are the following elements ... 

The biosensor and response system used a tiered approach. Samples of airborne biological material were taken continuously by the Joint Biological Point Detection System (JBPDS) equipment, which was not commercially available. Operation of these systems was monitored continuously at a separate control facility. Initial detection by the JBPDS equipment was followed by a second-tier assay analysis that, if positive, would result in physical collection of sampled material for additional analysis off-site. The confirmed second-tier analysis would result in notification of JBPDS leadership and shipment of a sample to the Utah Department of Health for further laboratory analysis. Because the confirmatory test would take 12-24 hours to complete, the primary function of the higher-tiered detection was to define treatment and decontamination responses (LP-3 options). Change in building or HVAC operation on the fifth and sixth floors would not be initiated until the Utah Department of Health analysis confirmed detection of a biological threat agent. 

The technique of postcolumn immunodetection involves the use of an lAC column that is attached to the exit of an analytical HPLC system. The lAC column in this approach serves to collect and retain a specific analyte from the HPLC column eluent for later detection. Both the on-off mode and immunoassay formats of I AC have been used as strategies for postcolumn immunodetection. The most common of these approaches is the one-site immunometric assay. One reason for this is that the immobilized analog columns in one-site immunometric assays often have a much more flexible selection of elution conditions than immobilized antibody columns. Another reason is that one-site immunometric columns can usually be used for many sample injections before they are eluted and regenerated, which helps to decrease the overall analysis time associated with their use in postcolumn detection. 

Oysters were thawed, opened with a clean Icnife, the liquid drained off, and a composite of several whole oysters collected. The entire sample of each site was homogenized and divided into four subsamples. Two were subjected to the analytical scheme, the third archived and frozen for further analysis, if necessary, and the fourth dried at 103°C to obtain the dry weight. 

Non-methane volatile organie eompounds (NMVOC) were measured at various sites representing different areas and different emission sources in the city of Wuppertal, Germany. The measurements covered volatile hydrocarbons in the range of C2-C10 and oxygenated hydrocarbons such as alcohols, ketones and esters. Samples were collected using Carbotrap and Carbosieve Sill solid adsorption tubes and analysed off-line by thermal desorption and GC-FID analysis. Measurement results were used to create the input data for the source apportionment analysis with the Chemical Mass Balance Modelling technique. Emission profiles for traffic and solvent use were calculated. 

In some cases, where the peptide mass alone is insufficient for definitive assignment, or if site-specific information about a particular amino acid position or modification is required, the peak may be collected (i.e., the eluate containing the peptide of interest) and subjected to further analysis, such as off-line high-resolution tandem MS (MS/MS) sequencing with collision-induced dissociation (CID) or electron-transfer...
