Sort with args from array

This is my $args:

$args=array(
    'post_status'       => 'publish',
    'post_type'         => 'products',
    'tax_query'         => array(
        array(
            'taxonomy'  => 'product_categories',
            'terms'     => explode(',', $groups_separated),
            'field'     => 'slug',
        )
    ),
    'posts_per_page'	=> 30
);

I would like to sort $args by the order of the terms that is being passed to it in $groups_separated

Is this possible? If so, how would I go about it?
