Polícia Científica do PR inova com aparelho de RMN forense

A Seção de Química Forense da Polícia Científica do Paraná (PCIPR) passou a contar com um moderno espectrômetro de Ressonância Magnética Nuclear (RMN) para identificar entorpecentes, remédios e mercadorias falsificadas ou adulteradas, a exemplo de azeites, vinhos e outras bebidas alcoólicas.

Inovação na perícia estadual Com a incorporação do aparelho Bruker Fourier 80, o órgão paranaense faz história ao se tornar a primeira Polícia Científica estadual do Brasil a adotar tal recurso tecnológico, antes restrito à atuação da Polícia Federal no cenário da perícia oficial do país.

Detalhes técnicos da tecnologia O dispositivo emprega a técnica de Ressonância Magnética Nuclear para entregar dados detalhados sobre a estrutura molecular de variados compostos químicos, potencializando a caracterização de substâncias e somando forças aos demais métodos laboratoriais já empregados.

Aplicações práticas em laboratório Entre as utilidades do aparelho estão a checagem de entorpecentes, a detecção de substâncias psicoativas inéditas e a verificação de farmácos, além de examinar itens alimentícios e bebidas para flagrar fraudes em produtos amplamente consumidos no mercado.

Declaração oficial sobre o avanço “Amplia o escopo de exames periciais e oferece novas possibilidades para a identificação e a caracterização de substâncias. Fortalecemos a produção de provas técnico-científicas e ampliamos o suporte aos procedimentos criminais, contribuindo para que as autoridades tenham informações qualificadas para a correta elucidação dos casos”, afirma o diretor-geral da PCIPR, Ciro Pimenta.

Otimização de procedimentos periciais A ferramenta também serve para agilizar certas rotinas de laboratório e sugerir caminhos para investigações específicas, dependendo da natureza dos materiais avaliados pelas equipes técnicas.

Palavra da chefia forense “Ele pode ser utilizado na identificação de drogas, medicamentos, solventes e substâncias desconhecidas, além de ajudar na análise de misturas. É uma ferramenta que complementa os equipamentos já existentes no laboratório e amplia nossas possibilidades de investigação, permitindo análises mais completas e resultados mais confiáveis”, explica Gabriela de Moraes Pinto, chefe da Química Forense da PCIPR.

Capacitação e integração de redes Para que o equipamento passe a integrar o dia a dia do laboratório, a instituição realiza processos de validação de metodologias e treinamento técnico, visando atender a rigorosos padrões de qualidade e rastreabilidade.

Visão acadêmica e cooperação Segundo Caroline Da Ros, coordenadora-geral do NAPI Segurança Pública e Ciências Forenses e diretora do Setor de Ciências Exatas da Universidade Federal do Paraná (UFPR), o aparelho representa um marco para o fortalecimento da ciência forense no Brasil.

“Além de ampliar significativamente as possibilidades de aplicação da Ressonância Magnética Nuclear em análises periciais, a iniciativa demonstra o pioneirismo da Polícia Científica do Paraná e sua visão estratégica de futuro, ao investir em tecnologias inovadoras e em um modelo de atuação colaborativa”, afirma.

A especialista destaca ainda a relevância da cooperação entre órgãos. “É uma conquista que vai muito além da aquisição de um equipamento: é um avanço na consolidação de uma ciência forense moderna, integrada e conectada aos melhores padrões internacionais”, diz.

Investimento financeiro no projeto Para viabilizar a chegada do Bruker Fourier 80, o investimento total foi de aproximadamente R$ 2 milhões, montante viabilizado por meio de repasses financeiros diretos da Loteria do Estado do Paraná (Lotopar).
