Sample transport kit

Sample Transport Kits 12 from the first Conference of ... 

The list of approved equipment contains two sample transport containers designed for the transport of samples for off-site analysis. The two containers are labelled as Targe- and small sample transport kits (Pictures 3 and 4) and both are designed to fulfill the requirements for air transport [IATA (International Air Transport Association) provision A106] (6) and international standards for road, railway, and sea transport. The large container has been designed and tested by the United States and the small container by the United Kingdom. Therefore, the two containers are frequently referred to as US and UK containers.

Sample transport kits are designed to fulfil the requirements for air transport of OPCW samples for off-site analysis under International Air Transport Association (IATA) provision 106 and international standards for road, railway, and sea transport. 

OPCW equipment includes two different types of sample transport kits (see the pictures in Chapter 2). 

The sample preparation kit (Picture 2) holds all equipment necessary to prepare the samples for GC/MS analysis on-site in four transport boxes (flight cases). It contains everything from the pH paper to the laboratory coat including the chemicals to conduct the sample preparation procedures. A reduced version of the sample preparation kit packaged in two pelli cases is available for inspections where this will suffice. 

An additional part of the sample collection kit are solvents (dichloromethane, methanol, water) and decontamination solutions. Solvents are necessary -in accordance with approved procedures - to collect wipe samples. These solvents need to be transported as dangerous goods, which require special transport arrangements. 

A large-sample transport container that may hold a maximum of 350 mL of any material. The outer transport packing of the kit is a conventional 200 L steel barrel, the weight of the kit is approximately 85 kg. 

LCAT acts preferentially on lipids transported by HDL (so-called a-LCAT activity), but also on lipids transported by apoB-containing lipoproteins (so-called jS-LCAT activity) [58, 85]. In practice, LCAT activity is measured either as the activity required to esterify radioactive cholesterol that has been exogenously incorporated into native HDL or into artificial HDL-like particles (a-LCAT activity) or which has been equilibrated with endogenous lipoproteins of the plasma sample (cholesterol esterification rate, CER) [21, 58, 85]. Several variations of these assays have been reported, some of which are available as commercial test kits (e.g., Roar Biomedical, New York, USA). In addition, LCAT concentration can be determined by either laboratory-made tests or by a commercial ELISA kits [57]. However, the decrease in LCAT concentration is difficult to judge since it also decreases secondary to HDL deficiency due to causes other than LCAT deficiency. Plasma from patients with LCAT deficiency fails to esterify radioactive cholesterol provided by any substrate. By contrast, plasmas of patients with fish-eye disease show a near-normal cholesterol ester-fication rate but have a selective inability to esterify radioactive cholesterol provided to plasma with native HDL or reconstituted HDL (a-LCAT activity) [58, 85]. 

With the exception of portable on-site testing kits, analytical equipment is rarely sited adjacent to the sampling point. Consideration should be given to the need for sample storage and transportation. For unstable samples it may be appropriate to stabilise the sample in some way before analysis can be carried out, e.g. this may involve chilling the sample. 

The different types of field measurement systems are summarized in Figure 1.3.1 (Greenwood et al., 2007a). They are all performed directly in the field. On-line and in-field systems (portable or transportable equipment, chemical tests kits and immunoassays tests kits) require a sampling step (spot sampling, sampling belt). Some... 

Different types of organisms such as daphnia, mussels, algae, and fish have been extensively incorporated in toxicity tests for water assessment systems [65], Most of these assays are developed as test systems with few as laboratory-based sensor systems. Membranes with their active enzyme system have also been implemented in the development of toxicity kits and sensors. An example is the MitoScan Kit (Harvard BioScience, Inc., Holliston, MA), which uses fragmented inner mitochondrial membrane vesicles isolated from beef heart (EPA, 2005 [9]). The submito-chondrial particles contain complexes of enzymes responsible for electron transport and oxidative phosphorylation. When specific toxins are in the sample, the enzyme reactions are slowed or inhibited, and these are monitored spectophotometrically at 340 mn. This is still in a bioassay test kit format but may be developed to optical sensor system. 

The CIM disks, with low-volume monolith stationary phase, used in this application allowed the desired separation of the analyte under low-pressure conditions. The use of a mixing chamber and the precise control of timing allowed the inline preparation of the necessary high number of standard solution mixtures for the multivariate calibration. The mixing chamber also provided a homogeneous mixture before the transport to the detector. The large sampled volume (1 mL) allowed the recording of spectra without dispersion effects (D = 1). Samples were diluted and their pH was adjusted to 8.5 before injection. Nevertheless, validation for the tartaric acid concentration was not possible with the enzymatic kits used in this work.
