New devices and equipment replenished an instrument pool of the Limnological Institute of Siberian Branch of the Russian Academy of Sciences.

Analytical set to determine the chemical composition of water, soil, bottom sediments and biota based on SUPEC 7000 Inductively Coupled Plasma Mass Spectrometer with a water treatment module, a module for samples thermal decomposition and an argon purification system.

Main advantages:

На основе аэродинамического моделирования на стыке термической плазмы и вакуума оптимизируется ионный интерфейс, и чувствительность ICP-MS увеличивается в 3-5 раз, а предел обнаружения до ppt. Благодаря оперативной системе разбавления аргоном (AGOD), которая повышает устойчивость SUPEC 7000 к матрице, можно напрямую вводить образцы с содержанием солей до 10%. Уникальный молибденовый квадруполь обеспечивает наилучшее качество и стабильность осей. В настоящее время этот прибор является единственным, который может работать на борту транспортных средств.
Sensitivity: ⁷Li 10, ⁵⁹Co 20, ¹¹⁵In 60, ²³⁸U 80Mcps/ppm. Detection limits: ⁷Li10, ⁵⁹Co10, ¹¹⁵In2, ²³⁸U2 ng/l. The ratio of oxides, double-charged ions (¹⁵⁶CeO⁺/¹⁴⁰Ce⁺, ⁷⁰Ce⁺⁺/¹⁴⁰Ce⁺) is less than 3%. Short-term stability (20 min) (⁷Li, ⁵⁹Co, ¹¹⁵In, ²³⁸U) is no more than 2%.

Automated black carbon analyzer ВАС-10 from Shenyang Chemetech Co., Ltd.

A multispectral monitor analyzer BAC-10 with the optical attenuation method, which uses the absorption characteristics of soot aerosols adsorbed on a striped quartz filter paper in various optical ranges to monitor the total amount of soot aerosols in real time in the atmosphere and in premises. Specifications: range limits 0-1000 μg/m3, light source wavelength from 370 to 940 nm. Lower limit of detection <55 ng/m3. Built-in humidity control system enables to reduce humidity impact on measurement results. Simple control and stable operation with minimal maintenance; automatic restart in case of energy tripping.

Universal hydroacoustic Doppler current profilers Aquadopp Profiler (ADCP). The purchased 2 MHz frequency version has a current profiling range of up to 12 m in normal mode and up to 2 m in high-resolution mode. The devices can work both offline and online with data transmission by cable. According to the measurement data it is possible to calculate the dissipation rates of turbulent kinetic energy, and when using profilers in pairs, to obtain the components of the Reynolds turbulent stress tensor in the high-resolution mode.

Temperature loggers (RBRsolo³ T) – ) are one of the most compact, lightweight and cross-functional single-channel temperature recorders that measure at a frequency of up to 2 Hz, have large memory amount and can work up to two years with a single battery. Temperature measurement accuracy is ±0,002°C.

Expedition vehicle to support field research conducted on the ice of Lake Baikal.
