Laboratory Methods. ELITE will ensure that all components and in-process release testing used to manufacture the Product(s) meets the specifications. At least one test (ID) to verify the identity of each batch of incoming material will be conducted. A supplier C of A or C of C may be referenced instead of performing other tests, provided that a supplier evaluation program is in force. ELITE’s internal Quality unit will approve all test results.
Laboratory Methods. Laboratory work will include standard processing and cataloguing of the materials recovered in the field, and special studies to address the program’s research issues.
Laboratory Methods. The official laboratory shall use methods that comply with Article 34 of Regulation (EU) 2017/625.
Laboratory Methods. Laboratories shall use methods that comply with Article 11 of Regulation (EC) No. 882/2004. Laboratories performing the same analysis should use consistent methods to ensure comparability and consistency of results nationally.
Laboratory Methods. Laboratory procedures for this project included two components: 1) instrument calibration, testing and preparation, and 2) analysis of sediment and water samples from the field site. All instrumentation was calibrated, prior to deployment, by the Coastal Studies Institute Field Support Group in their testing facilities. Since optical backscatter sensors are more sensitive to fine than to coarse sediment, while the reverse is true for acoustic systems, appropriate field conversion factors were established using bottom sediment from the study sites. This procedure consisted of exposing the sensors to a series of uniformly-stirred mixtures of distilled water and known concentrations of field sediment. The voltage output from the sensors was then related to the sediment concentration by using regression to fit a calibration curve to a scatter-plot of these variables. Since the field data from the optical backscatter sensors were ultimately found to be faulty, OBS calibration results will not be discussed. Field data from the ADV’s appeared to be reliable, however, and as such, the electronic signal strength was converted from the calibration curve obtained in the laboratory, which took the form: C=7.20197 x 10-10 (10 0.043SS) (3.1) where C is the volumetric concentration of sediment and SS is the ADV signal strength. Dry sieving at 0.25 φintervals was conducted to determine the grain-size composition of the samples of bottom sediment. The water samples, collected at the surface and at 0.5, 2 and 4 m above the bed, were filtered through 0.7-m paper using a pump-operated filtration system, dried in an oven at 60oC, and weighed to determine the sediment concentration. Data Processing and Analytical Methods
Laboratory Methods. The official laboratories shall use methods that comply with Article 34 of Regulation (EU) 2017/625. Official laboratories within the Food Safety Laboratory Service performing the same analysis should strive to use comparable methods to ensure consistency of results nationally or adopt other strategies to ensure this consistency. Where similar methods are undertaken, there should also be consistency with regard to the sample quantities requested by the Food Safety Laboratory Service, sample storage and preparation.
Laboratory Methods. Materials collected during field work will undergo a variety of laboratory analysis to address the research questions. The types of analysis conducted will be dependent on the artifacts and samples collected during field work, but may include radiocarbon dating of charcoal and bone samples, x-ray fluorescence, and hydration analysis if obsidian artifacts are collected; studies of faunal material (e.g., species identification, evidence of butchering or modification); studies of macrobotanical remains from flotation samples; lithic analysis (e.g., identifying artifacts as diagnostic to specific cultures and/or time periods, identifying raw materials represented among the assemblage); and trace element analysis of copper, if any is identified during the investigations. Though not exhaustive, examples of analyses to be conducted as part of data recovery are provided below.8 The specific types of analyses will be refined in the amended Treatment Plan. Flaked Stone Artifacts Flaked stone analyses should have two main objectives: documenting the flaked stone assemblages at sites/loci, and identifying the kinds of lithic-reduction activities that occurred there. Toward this end, archaeologists will measure and weigh all formed tools, record edge type and modification, and document tool condition (e.g., whole, distal fragment, margin). Debitage samples from single component areas will receive technological analysis designed to identify the types of flaking debris and reduction activities represented at different sites. Analysis may also include identifying procurement sources for the lithic material. Other Artifacts A variety of other artifacts, including beads, ornaments, bone implements/tools, quartz crystals, ceramics, and perishable remains (e.g., cordage, basketry), may also be recovered during the course of the Project. If beads are encountered, archaeologists will record material, color, basic measurements that include length and width (or diameter), thickness (or curvature), and perforation size and type (e.g., conical, biconical, conical with retouch from the opposite side). Additional observations will include the material employed, details of manufacture (e.g., wire- wound, edge ground, scored and snapped), condition, color and tinge, and whether or not the piece appears to have been worn (e.g., asymmetrical wear of the perforation or evidence of polish). Archaeologists will measure bone tools and sort them into functional categories based on their morph...
