상기 시험관 교반기(101)는 시험관(105) 내에 들어 있는 잔류 농약 검사와 관련된 시약과 잔류 농약 검사 대상의 농작물 샘플(시료)을 교반해 줌으로써 시약과 시료가 골고루 섞이게 한다. 이 시험관 교반기(101)는 상기 항온 수조(102)와 탈착 가능하도록 몸체의 상부에 항온 수조(102)와의 결합을 위한 결합부(307)(도 3참조)가 마련된다. 특히, 이 시험관 교반기(101)는 시험관(105)에 들어 있는 시약과 시료를 교반해주는 기능을 가질 뿐만이 아니라, 항온 수조(102)의 항온 유지를 위한 온도 조절 기능도 갖는다.The test tube stirrer 101 stirs the reagents related to the residual pesticide test in the test tube 105 and the crop sample (sample) for the residual pesticide test to mix the reagent and the sample evenly. The test tube stirrer 101 is provided with a coupling portion 307 (see FIG. 3) for coupling with the constant temperature water tank 102 at the top of the body so as to be detachable from the constant temperature water tank 102. In particular, the test tube stirrer 101 not only has the function of stirring the reagent and the sample contained in the test tube 105, but also has a temperature control function for maintaining the constant temperature of the constant temperature water tank (102).

상기 항온 수조(102)는 상기 시험관 교반기(101)에 의해 교반된 내용물을 담고 있는 시험관(105)을 항온(예를 들면, 37℃)에서 일정 시간 동안 반응시켜 주는 역할을 한다. 이 항온 수조(102)는 전체적으로 원통형의 구조를 가지며, 그 상면부에는 다수의 시험관을 수용하기 위한 시험관 삽입홀(102h)이 형성되어 있는 시험관 장착부(102s)가 마련되고, 그 하면부에는 상기 시험관 교반기(101)와의 결합을 위한 탈착 가능한 구조의 결합부(미도시)가 마련된다.The constant temperature water tank 102 serves to react the test tube 105 containing the contents stirred by the test tube stirrer 101 at a constant temperature (for example, 37 ° C.) for a predetermined time.

상기 분광 광도계(103)는 항온 수조(102)에 일정 시간 동안 반응시킨 시험관 (105) 내의 용액에 대한 분광 특성을 측정한다. 이 분광 광도계(103)는 일반적인 분광 광도계의 하드웨어 구성을 거의 동일하게 갖는다. 따라서, 내부 구성에 대한 구체적인 설명은 생략하기로 한다. 다만, 본 발명에서의 분광 광도계(103)는 분석 대상물에 대한 흡광도(기준물질과 시료의 흡광차이, 즉 저해율)를 자동으로 계산하여 LCD 표시창(302)(도 3 참조)에 표시하는 기능을 특징적으로 더 구비한다. 여기서, 이와 같은 저해율 자동 계산 알고리즘은 하나의 소프트웨어 프로그램으로서 분광 광도계 시스템 설계자에 의해 미리 작성되어 시스템 내부의 메모리(미도시)에 저장된다. 여기서, 또한 이와 같은 분광 광도계(103)와 상기 시험관 교반기(101)는 도 3 및 도 4에 도시된 바와 같이, 하나의 하우징(301) 내에 일체로 마련된다. 따라서, 필요시에는 이 일체형 장비를 가방에 넣어 휴대함으로써 장소에 구애됨없이 자유롭게 장비를 가지고 다닐 수 있게 된다. 도 3 및 도 4에서 참조 번호 303은 RPM 조정 스위치, 304는 전원 온/오프 스위치, 305는 온도계, 306은 시험관의 용액을 채취한 사각 시험관을 꽂기 위한 홀의 뚜껑을 각각 나타낸다.The spectrophotometer 103 measures the spectral characteristics of the solution in the test tube 105 reacted with the constant temperature water tank 102 for a predetermined time. This spectrophotometer 103 has almost the same hardware configuration of a general spectrophotometer. Therefore, a detailed description of the internal configuration will be omitted. However, the spectrophotometer 103 of the present invention is characterized by a function of automatically calculating the absorbance (absorption difference, i.e., inhibition rate) between the reference material and the sample for analyte and displaying it on the LCD display window 302 (see FIG. 3). It is further equipped with. Here, such an automatic inhibition rate calculation algorithm is prepared in advance by the spectrophotometer system designer as a software program and stored in a memory (not shown) inside the system. Here, such a spectrophotometer 103 and the test tube stirrer 101 are integrally provided in one housing 301, as shown in FIGS. 3 and 4. Therefore, if necessary, the integrated equipment can be carried in a bag so that the equipment can be carried freely regardless of the place. In FIG. 3 and FIG. 4, reference numeral 303 denotes an RPM control switch, 304 a power on / off switch, 305 a thermometer, and 306 a hole cap for inserting a square test tube from which a solution of a test tube is collected.

상기 시약분취용 초자기구(104)는 상기 시험관에 시약을 분취하기 위해 사용된다.The reagent preparative instrument 104 is used to aliquot the reagent into the test tube.

그러면, 이상과 같은 구성의 본 발명에 따른 휴대용 속성 잔류 농약 분석장치를 이용하여 농작물의 잔류 농약을 분석하는 과정에 대해 간략히 설명해 보기로 한다.Then, a brief description will be given of a process of analyzing the residual pesticides of the crops using the portable attribute residual pesticide analysis apparatus according to the present invention as described above.

본 발명의 휴대용 속성 잔류 농약 분석장치를 이용하여 농작물의 잔류 농약을 분석하기 위해서는 우선 시약이 준비되어야 한다. 이때, 시약으로는 효소 용액(효소에 10ml 증류수를 넣고 용해), 기질 용액(기질에 10ml 증류수를 넣고 용해), 인산완충액(1L 플라스크에 인산을 넣고 증류수로 1L 눈금만큼 채워서 용해), 발색 시약 50ml, 반응정지액(반응정지액에 45ml 증류수를 넣고 용해) 및 브롬수가 사용된다.In order to analyze the residual pesticides of the crop using the portable rapid residual pesticide analysis apparatus of the present invention, a reagent must first be prepared. At this time, as the reagent, the enzyme solution (10ml distilled water into the enzyme to dissolve), the substrate solution (10ml distilled water into the substrate to dissolve), the phosphate buffer solution (put the phosphoric acid in 1L flask and fill with 1L distilled water), 50ml color development reagent , Reaction stop solution (45ml distilled water is added to the reaction stop solution and dissolved) and bromine water are used.

이렇게 하여 시약이 준비되면, 시료를 적당한 크기로 절단하여 시험관(105)에 넣고, 각 시험관(105)에 메탄올을 소정량(예컨대, 2ml)씩 넣는다. 그런 후, 각 시험관(105)에 브롬수 20㎕씩 넣고, 약 20∼30초간 혼합한 다음 2분간 정치한다. 그런 다음, 빈 시험관(105)에 추출액만 옮겨 담는다. 다른 빈 시험관(105)(이때, 시험관은 시료수×2+2개의 시험관을 준비한다. 이때, 2개는 블랭크(+,-) 시험관이다.)에 인산완충액(5ml), 상기 시료추출액(100㎕), 효소용액(100㎕)을 넣어 혼합 후 37℃ 항온 수조(102)에서 5분간 인큐베이션(incubation) 시킨다. 그리고, 각 시험관(105)에 기질용액 100㎕를 넣고 혼합 후, 37℃ 항온 수조(102)에서 10분간 인큐베이션 시킨다. 그런 후, 각 시험관(105)에 반응정지액 100㎕를 넣고 혼합 후, 37℃ 항온 수조(102)에서 2분간 인큐베이션 시킨다. 그리고, 각 시험관(105)에 발색시약 100㎕를 넣고 혼합 후 시험관(105)을 꺼내어, 분광 광도계(103)에 의해 흡광도를 측정한다. 즉, 분광 광도계(103)의 파장을 412nm로 조정한 후, 먼저 플러스(+) 시험관 용액을 큐빗(cuvette)에 옮겨서 측정한다. 그런 후, 마이너스(-) 시험관 용액을 큐빗에 옮겨서 측정한다. 그런 다음, 시료 시험관 용액을 큐빗에 옮겨서 흡광도를 측정한다. 그런 후, 측정 결과를 바탕으로 저해율을 계산하게 된다. 이때, 이 저해율은 시스템 메모리에 미리 저장되어 있는 저해율 계산 알고리즘에 의해 자동으로 계산되며, 그 결과가 최종적으로 LCD 표시창(302)을 통해 표시된다. 이렇게 하여 임의의 분석 대상물에 대하여 잔류 농약 정도를 1차적으로 분석한 후, 일정 기준 저해율을 초과한 분석 대상물(농작물)에 대해서는 2차로 정밀 분석을 실시하게 된다.In this way, when a reagent is prepared, a sample is cut into an appropriate size and put into a test tube 105, and a predetermined amount (for example, 2 ml) of methanol is put into each test tube 105. Thereafter, 20 µl of bromine water was added to each test tube 105, mixed for about 20 to 30 seconds, and allowed to stand for 2 minutes. Then, only the extract is transferred to the empty test tube 105. Another empty test tube 105 (at this time, the test tube is prepared by the number of samples × 2 + 2, wherein two are blank (+,-) test tubes) in a phosphate buffer solution (5ml), the sample extract solution (100 Μl) and the enzyme solution (100μl) were added and incubated for 5 minutes in a constant temperature water bath 102 at 37 ° C. Then, 100 μl of substrate solution is added to each test tube 105, and then mixed and incubated for 10 minutes in a 37 ° C. constant temperature water bath 102. Thereafter, 100 µl of the reaction stopper solution was added to each test tube 105, followed by incubation for 2 minutes in a constant temperature water bath 102 at 37 ° C. Then, 100 µl of the color developing reagent is added to each test tube 105, and after mixing, the test tube 105 is taken out, and the absorbance is measured by the spectrophotometer 103. That is, after adjusting the wavelength of the spectrophotometer 103 to 412 nm, a positive (+) test tube solution is first transferred to a cuvette and measured. The negative (-) test tube solution is then transferred to the qubit for measurement. Then, the sample test tube solution is transferred to a qubit to measure absorbance. The inhibition rate is then calculated based on the measurement results. At this time, the inhibition rate is automatically calculated by the inhibition rate calculation algorithm stored in the system memory in advance, and the result is finally displayed on the LCD display window 302. In this way, the residual pesticide level is primarily analyzed for any analyte, and the analytical target (crop) that exceeds a certain standard inhibition rate is subjected to the second precision analysis.

이상의 설명에서와 같은 본 발명에 따른 휴대용 속성 잔류 농약 분석장치에 의하면, 비교적 부피 및 중량이 큰 종래의 분광 광도계와 시험관 교반기를 부피와 중량을 줄여 하나의 하우징 내에 마련하여 일체화 시킴으로써 휴대가 간편하여 실험실내에서 뿐만이 아니라 농작물의 생산 현장에서 직접 농작물의 잔류 농약을 신속하게 분석할 수 있는 장점이 있다. 또한, 종래에는 각각의 시험관을 매번 교반시키는 것에 반해, 본 발명에서는 다수의 시험관을 동시에 교반시켜 줌으로써 시험시간을 한층 단축할 수 있고, 저해율을 자동으로 계산하여 표시해 줌으로써 필요한 결과를 얻기가 용이하다.According to the portable fast-acting pesticide analysis apparatus according to the present invention as described above, the conventional portable spectrophotometer and test tube stirrer with relatively large volume and weight are provided in one housing by reducing the volume and weight so as to integrate and carry out experiments. There is an advantage in that it is possible to quickly analyze residual pesticides of crops not only indoors but also directly at the production site of the crops. In addition, conventionally, while stirring each test tube each time, in the present invention, the test time can be further shortened by simultaneously stirring a plurality of test tubes, and it is easy to obtain necessary results by automatically calculating and displaying the inhibition rate.
