Outside the appraisal room!
Shao Ming, Zhang Chuanyi and other police officers who were watching the scene all noticed that Director Da Ma's expression had changed very obviously.
Before, when Shen Ting first entered the appraisal room, there was still a hint of doubt in his eyes.
But this suspicion disappeared without a trace after Chen Ting pointed to the abnormal peak in the graph.
Director Dama's look showed obvious surprise.
It seemed that he had not expected that such a young Shen Ting could see the same abnormal peak as him.
From then on, although Director Da Ma was already in his forties or fifties, he no longer treated Shen Ting with the attitude of an elder towards a younger person.
But they are peers with equal strength!
only!
As Shen Ting instructed him to separate and identify the blood samples...
This attitude towards peer interaction is also changing rapidly.
Director Dama's expression became more and more humble.
It seemed that his figure was becoming smaller and smaller in front of Shen Ting.
And in his eyes, Shen Ting became taller and taller.
Director Da Ma had to tilt his head back hard to look up at Shen Ting.
Until the end, when the identification result of ring crystals was obtained, Director Dama's expression had completely turned into admiration.
When Chen Ting pointed out the second special peak to be identified, Director Dama discovered that it was the same abnormal peak he had discovered!
He no longer thought about Shen Ting’s eyesight, which was on par with his own.
There was an obvious hint of pride and complacency in his expression.
It’s not about being proud or complacent about Shen Ting!
But he was proud of himself!
Shen Ting's appraisal level is so high that Director Da Ma can't even imagine it.
But he could see from the graph the same abnormal wave peaks as Shen Ting's.
Moreover, there are two abnormal peaks!
He felt that he was really amazing!
…
"It looks like Director Ma is impressed by Shen Ting?"
"Did Shen Ting really identify a special substance?"
"Look at Director Ma's posture. He doesn't look like the director of the physical evidence identification room at all. He looks like Shen Ting's subordinate!"
"The key is, being Shen Ting's younger brother, listening to his instructions, and seeming to enjoy it."
“I remember that Director Xiao Ma of our bureau had the same expression when he was cooperating with Shen Ting in the later stages of spore and pollen identification.”
…
Outside the appraisal room, a group of police officers were surprised and curious.
I was surprised at the change in Director Dama.
I am even more curious about what Shen Ting has identified.
Can it bring a breakthrough to the case?
at the same time!
The second special substance was also successfully separated and identified.
Director Da Ma snatched the appraisal report from the printer, without even looking at it, and handed it directly to Shen Ting.
Shen Ting took a look and immediately knew what was going on.
This is an arsenic-protein complex!
The key is!
These two special substances, combined with the three special substances identified previously, do form a certain specificity.
“Don’t rush to conclusions!
Let's identify the third special substance first."
At this time!
Director Dama next to him looked at Shen Ting eagerly and asked:
"Brother Shen, where is the abnormal waveform corresponding to the third special substance you mentioned?"
Shen Ting took out the energy spectrum of the blood sample and pointed to a peak:
"here!"
Director Da Ma had long wanted to know which abnormality he had missed, so he quickly looked over and then frowned.
"Ah? Still here?"
The blood energy spectrum that Shen Ting took was obtained on an electron microprobe.
The principle is to bombard the sample with a focused electron beam, causing the elements in it to produce characteristic X-rays.
Then use an energy spectrometer to measure the intensity and wavelength of the characteristic X-rays.
In this way, the types and quantities of elements contained in the sample can be determined.
The peak that Shen Ting pointed out corresponds to the element arsenic!
What surprised Director Dama was that the abnormal waveform that Shen Ting pointed out for the second time was clearly this one.
So, the arsenic-protein complex was finally identified...
