Methods for preparing samples for mass spectrometry. In one embodiment the carrier gas type and flow rate is continuously exchanged to facilitate high speed, high sensitivity compound specific isotope analysis. Samples are injected into a gas chromatograph that uses H2 as the carrier gas. The gas stream exiting the gas chormatograph is passed through a combustion system in which H2 and the samples are combusted, simultaneously and totally, to oxidize the sample to C02 and/or N2 gas, and to convert H2 gas to water vapor. Water vapor is removed using a water separator. Therefore, combustion serves the dual purpose of preparing the samples for isotopic analysis and converting H2 to water vapor, which can be easily separated out. An inert carrier gas is used to convey the C02 and N2 to a mass spectrometer where the isotopic composition (e.g. 14C or 15N) is determined.

APPARATUS, SYSTEMS AND METHODS FOR ENHANCED MULTI-CARRIER BASED UNDERWATER ACOUSTIC COMMUNICATIONS
Advantageous OFDM-based underwater acoustic (UWA) apparatus, systems and methods are provided according to the present disclosure. In general, OFDM transmissions over UWA channels encounter frequency-dependent Doppler drifts that destroy the orthogonality among OFDM subcarriers. The disclosed apparatus, systems, and methods use a two-step approach to mitigate frequency-dependent Doppler drifts for zero-padded OFDM transmissions over fast-varying channels: (1) non-uniform Doppler compensation via resampling to convert a 'wideband' problem into a 'narrowband' problem; and (2) high-resolution uniform compensation on the residual Doppler. The disclosed apparatus, systems and methods are based on block- by-block processing and do not rely on channel dependence across OFDM blocks. Thus, the disclosed apparatus, systems and methods are advantageously applicable for fast-varying UWA channels.
The systems and methods described herein include, among other things, systems capable of being deployed for long periods of time in oceanic, subsurface and atmospheric environments. The systems typically include mass spectrometers to measure low molecular weight gases dissolved in the water and volatile chemicals in air and water, and can move through the ocean, subsurface and atmospheric environment to take samples over a large geographic area. Additionally, these mass spectrometer devices are small and require little power and thereby facilitate the development of sample collection devices that can be placed at a remote location and operated for a substantial period of time from an on-board power supply such as a battery or a fuel cell. Such small and lightweight mass spectrometer devices when combined with low power AUVs (Autonomous Underwater Vehicles) and other manned and un-manned vehicles, can take samples over substantial distances and for a substantial period of time.

Upon separation of the fuse, a cable payout system pays out an optical fiber that keeps the underwater vehicle, typically a robotic craft, in communication with the surface vessel (116). The relatively light weight glass fiber may be reinforced and extended to lengths greater than 40km allowing deep-sea exploration at depths up to 11,000m.
