INSTRUMENTATION
SolariX FT-ICR MS
In the Laboratory of Petroleomics and Forensic Chemistry, FT-ICR MS has a magnetic field of 9.4 T and has four commercial sources of ionization, three of which are atmospheric pressure pressure (APPI), atmospheric pressure chemical ionisation (APCI), and electrospray ionisation (ESI)) and one matrix assisted laser assisted desorption ionization (MALDI)).
Fourier ion cyclotronic resonance and transformal mass spectrometry (FT-ICR MS) is a technique that allows molecular determination of simple (synthesis product, for example) and complex (such as petroleum) matrices due to their high spectral resolution power. From this technique, spectra are obtained whose signal values correspond to the mass/load ratio of ions generated from different sources. Each ion is identified based on the cyclotronic frequency that can be detected when inducing current in electrode plates and by a sensitive and accurate frequency measurement, the high resolution power is obtained. A strong, fixed magnetic field provided by the superconducting magnet is used in this instrument. The ability to couple different sources of ionization to the equipment and the possibility of direct injection analysis of several matrices (polar, apolar, with condensed heteroatoms or cyclics) make this instrument a powerful tool in research laboratories. Due to its excellent performance, FT-ICR-MS is useful in the study of molecules in complex mixtures such as food, biomass, crude oil, waste, among others.

MicroNIR™ Pro Spectrometer System
The MicroNIR™ is a near infrared spectrometer, portable and compacto. The instrument consists of a light source consisting of a pair of vacuum tungsten lamps, a linear variable filter as a dispersing element, and a 16-bit analog-to-digital converter (ADC). It is operated coupled to a computer or tablets equipped with MicroNIR Pro software, so the user can collect spectra for the development of calibration models. The main applications of MicroNIR™ in the Laboratory of Petroleomics and Forensics are in clinical research, analysis of environmental samples, analysis of oil and fuels, forensic toxicology and food safety.

Smart Cloud AI Raman Spectrometer
The CloudMinds XI ™ is a portable Raman spectrometer, laser excitation of 785 nm. It is an instrument built using the Android CloudMinds Data A1 smartphone, which supports voice calls, emails, GPS location tracking and camera image capture. XI ™ can be operated as a standalone unit or connected by Bluetooth, Wi-Fi and clouds. In addition, the cloud-based data platform enables you to securely create a spectral library. Thus, it allows analyses to be performed outside the laboratory, with real-time monitoring and with minimal sample preparation. The main applications of CloudMinds XI ™ in the Laboratory of Petroleomics and Forensics are in clinical research, forensic toxicology and food safety.

Liofilizador
The lyophilizer is the equipment capable of promoting lyophilization, causing the water of a product to be removed, without it losing its properties. It has a component that allows to allocate the materials that will be submitted to the procedure, in addition to a tool that reduces the pressure around the product that is desired to dry. The equipment consists of a tray rack with transparent acrylic bell. Silicone rubber sealing ring. Anifolds/taps in nitrile rubber for pressure relief and open/close control, for freeze drying in bottles exposed to the environment and connected directly to the top in transparent acrylic for viewing.

APPS AND PROGRAMS
REDGIM
Redgim was created in 2016 by Prof. Dr. Thalles Ramon Rosa to quantify results obtained by thin layer chromatography using statistical tools. The paper entitled "Direct quantitative analysis of cocaine by thin layer chromatography plus a mobile phone and multivariate calibration: a cost-effective and rapid method" has been published and is available at https://pubs.rsc.org/en/content/articlelanding/2016/ay/c6ay02126c. Currently, the application performs analysis for pattern classification and multivariate regression. It's available for free download on Google Play (https://play.google.com/store/apps/details?id=com.labqui.app.forenseboy&hl=pt_BR).
