Bruker BEST NMR system	OBI_0000591	[The introduction of biological screening and combinatorial chemistry for chemical synthesis has also introduced new requirements for NMR automation, e.g., the use of well plates for sample input, increased demands on throughput, and the need for quick and simple interpretation of the acquired NMR data.]
Bruker 1mm MicroProbe	OBI_0000590	[Over the past few years there has been a significantly growing demand for miniaturization in all areas ofmodern research and development. Evoked by many exciting applications, there is a need for analytical methods which require less amounts of sample. Bruker BioSpin meets this challenge with a revolutionary NMR probe design: The 1mm MicroProbe. It operates with disposable 1mm capillary sample tubes and the sample volume of 5 microliters enables the use of lowest amounts of sample to run all high resolution NMR experiments with outstanding sensitivity and up to 16 times faster measurements. Due to the TXI-type probe design, the z-gradient coil and the automatic matching and tuning accessory, the 1mm MicroProbe can be used for a wide variety of NMR experiments. The key advantages of this probe include:n up to 4 times higher mass sensitivity than 5mm conventional probes (with respect to the same sample amount)n excellent solvent suppression propertiesn virtually no salt effectn discrete samples in tubes that can be sealed and storedn automation accessory for sample preparation and handling available.]
ozone-induced chemiluminescence detector	OBI_0000598	[Although there are many direct ozone chemiluminescent reactions with various gaseous molecules, the incorporation of a conversion step to convert various non-chemiluminescent analytes to a species capable of reacting with ozone to produce chemiluminescence broadens the horizon of this technique tremendously. The conversion of nearly all nitrogen- and sulfur-containing compounds to their respective chemiluminescent species for universal nitrogen and sulfur detection has made nitrogen/sulfur chemiluminescence detection the most widely used analytical methods based upon ozone-induced chemiluminescence. In addition to non-chromatographic applications, nitrogen/sulfur chemiluminescence detection has been adapted to various chromatographic techniques from gas chromatography to liquid and supercritical fluid chromatography as specialized element-specific detectors. The characteristics of these detectors are evaluated and compared to other element-selective detection techniques. The unique features of the chemiluminescence detectors have made them powerful tools in many diverse fields of analytical chemistry.]
pulsed amperometric detector	OBI_0000595	[A chromatography detector as used by high-performance anion exchange chromatography that provides sensitive and specific detection of carbohydrates. Pulsed Electrochemical Detection (PED) allows simple, sensitive, and direct detection of numerous polar aliphatic compounds, especially carbohydrates. This technique exploits the electrocatalytic activity of noble metal electrode surfaces to oxidize various polar functional groups. In PED, multi-step potential-time waveforms at Au and Pt electrodes realize amperometric/coulometric detection while maintaining uniform and reproducible electrode activity. The response mechanisms in PED are dominated by the surface properties of the electrode, and, as a consequence, members of each chemical class of compounds produce virtually identical voltammetric responses. Thus, the full potential is realized when combined with high performance liquid chromatography (HPLC).]

TNM pathologic distant metastasis findings are based on clinical findings supplemented by histopathologic examination of one or more tissue specimens acquired during surgery.]
